Abstract
Complex interactions between noncoordinating residues are significant yet commonly overlooked components of macromolecular catalyst function. While these interactions have been demonstrated to impact binding affinities and catalytic rates in metalloenzymes, the roles of similar structural elements in synthetic polymeric catalysts remain underexplored. Using a model Suzuki-Miyuara cross-coupling reaction, we performed a series of systematic studies to probe the interconnected effects of metal-ligand cross-links, electrostatic interactions, and local rigidity in polymer catalysts. To achieve this, a novel bifunctional triphenylphosphine acrylamide (BisTPPAm) monomer was synthesized and evaluated alongside an analogous monofunctional triphenylphosphine acrylamide (TPPAm). In model copolymer catalysts, increased initial reaction rates were observed for copolymers untethered by Pd complexation (BisTPPAm-containing) compared to Pd-cross-linked catalysts (TPPAm-containing). Further, incorporating local rigidity through secondary structure-like and electrostatic interactions revealed nonmonotonic relationships between composition and the reaction rate, demonstrating the potential for tunable behavior through secondary-sphere interactions. Finally, through rigorous cheminformatics featurization strategies and statistical modeling, we quantitated relationships between chemical descriptors of the substrate and reaction conditions on catalytic performance. Collectively, these results provide insights into relationships among the composition, structure, and function of protein-mimetic catalytic copolymers.

Abstract
Single-chain nanoparticles (SCNP) are a class of polymeric nanoparticles obtained from the intramolecular cross-linking of polymers bearing reactive pendant groups. The development of SCNP has drawn tremendous attention since the fabrication of SCNP mimics the self-folding behavior in natural biomacromolecules and is highly desirable for a variety of applications ranging from catalysis, nanomedicine, nanoreactors, and sensors. The versatility of novel chemistries available for SCNP synthesis has greatly expanded over the past decade. Significant progress was also made in the understanding of a structure-property relationship in the single-chain folding process. In this Viewpoint, we discuss the effect of precursor polymer topology on single polymer folding. We summarize the progress in SCNP of complex architectures and highlight unresolved issues in the field, such as scalability and topological purity of SCNP.

Abstract
We systematically investigated the roles of tail length on the self-assembly of shape amphiphiles composed of a hydrophobic polymer chain (tail) and a hydrophilic nanoparticle in selective solvent using Brownian dynamics simulations. The shape amphiphiles exhibited a variety of self-assembled aggregate morphologies which can be tuned by changing tail length (n) in combination with amphiphile concentration (φ) and system temperature (T*). Specifically, at high φ with T*=1.4, the morphology varied following the sequence "spheres → cylinders → vesicles" upon increasing n, agreeing well with experimental observations. At low φ with T*=1.4 or at high φ with T*=1.2, the morphology sequence becomes "spheres or spheres and cylinders mixture → cylinders → vesicles → spheres" upon increasing n, which has not been found experimentally. Two morphological phase diagrams depending on n and φ were constructed for T*=1.4 and 1.2, respectively. The rich phase behaviors on varying tail length could provide the feasible routes to fabricate target aggregate morphologies in various applications, especially for the vesicles with tunable thickness of membranes that are crucial in drug and gene delivery.

Abstract
The preparation of polymer nanoparticles with a uniform size and shape, beyond spheres, is an unresolved problem. Here we report a living aqueous catalytic polymerization, resulting in particles grown by a single active site and composed of a single ultra high molecular weight polyethylene (UHMWPE) chain. The control on a molecular level (Mw/Mn = 1.1–1.2) and at the same time on a particle level (PDI < 0.05) together with the immediate deposition of the growing chain on the growing nanocrystal results in a distinct evolution of the particle morphology over time. These uniform nanocrystals are obtained as concentrated aqueous dispersions of > 10 wt-% (N ≈ 1019 particles L−1) polymer content. Key to this robust procedure to single chain nanoparticles are long-lived water-stable Ni(II) catalysts that do not undergo any chain transfer. These findings are a relevant step towards polymer materials based on nanoparticle assembly. The formation of polymer nanoparticles with a uniform size and shape, beyond spheres, is an unresolved problem. Here the authors show a living aqueous catalytic polymerization forming single crystal particles grown by a single active site and composed of a single ultra high molecular weight polyethylene chain.

Abstract
We report the use of intramolecular cross-linking chemistry as a tool to control the self-assembly of amphiphilic diblock copolymers (di-BCPs). Two amphiphilic di-BCPs of poly( N, N'-dimethylacrylamide)- block-polystyrene (PDMA- b-PS) with photo-cross-linkable cinnamoyl groups in either hydrophobic or hydrophilic blocks were prepared using reversible addition-fragmentation chain transfer polymerization. Intramolecular photo-cross-linking of cinnamoyl groups led to the formation of tadpole-shaped polymer single-chain nanoparticles (SCNPs) consisting of a self-collapsed block as the "head" and an un-cross-linked block as the "tail". When intramolecular photo-cross-linking was carried out in hydrophobic PS blocks, a clear morphological transition from branched cylindrical micelles (for the linear di-BCP) to completely spherical micelles at a dimerization degree of ∼63% was observed. A pattern of morphological transitions from cylindrical micelles to spherical micelles is observed through stepwise downsizing the length of cylindrical micelles when increasing the self-collapse degree of PS blocks, whereas, in case of photo-cross-linking carried out in hydrophilic PDMA blocks, the size of micelles showed a dramatic increase due to the shift of hydrophobic-to-hydrophilic balance. When the cross-linking degree of PDMA blocks reached >60%, tadpole-shaped SCNPs assembled into nonconventional aggregates with a nonsmooth surface. Our results illustrate the impact of chain topologies on the self-assembly outcomes of amphiphilic di-BCPs, which likely opens a door to control the micellar morphologies from just one parent linear di-BCP, rather than resynthesizing BPCs with different volume fractions of the two blocks.

Abstract
Ultrafine single-chain tadpole polymers (SCTPs), containing an intrachain crosslinked globule and a pH-sensitive linear polymer chain, have been synthesized. Self-assembly of these polymers depends on the linear block length and the pH, at which the polymer is assembled. Although the SCTPs themselves exhibit a size that is consistent with a single-chain species, the self-assembled SCTPs were found to be substantially larger. Since the transition between these two structures is reversibly dependent on pH, we explored the possibility of utilizing these assemblies to achieve deep tissue penetration in tumors. Our results indicate that there is indeed a pH-dependent deep tissue penetration in ex vivo tumor multicellular spheroids. Moreover, the multi-tadpole assemblies (MTAs) can stably encapsulate hydrophobic molecules, which have been used to encapsulate paclitaxel (PTX). These PTX/MTAs show excellent therapeutic efficacy and biosafety in 4 T1 xenograft mouse models. The innovative multi-compartment aggregates are able to fulfill structure-related function transitions with the variation of microenvironment, which has potential to extremely enrich the design of sophisticated biological agents.

Abstract
Molecular nanoparticles have been used as building blocks in the synthesis of functional materials. The grand challenges in the synthesis of the functional materials are precise control of the structures and functionalities of the materials by using nanoparticles with different architectures and properties. Monotethered single-chain polymeric nanoparticles (SCPN) are a type of nanosized asymmetric particles formed by intramolecular cross-linking of linear diblock copolymer chains. Monotethered SCPNs can be used as elemental building blocks for the fabrication of well-defined advanced structures. In this research, synthesis of biohybrid materials based on coassembly of bovine serum albumin (BSA) molecules and monotethered SCPNs is investigated. Due to the asymmetric structure of the SCPNs, positively charged SCPNs and negatively charged protein molecules coassemble into biohybrid vesicles with SCPNs on the layers and protein molecules in the walls. The self-assembled structures were analyzed by using dynamic light scattering, transmission electron microscopy, cryo-transmission electron microscopy, and atomic force microscopy. The average size of the biohybrid vesicles can be controlled by the molar ratio of SCPNs to BSA. The protein molecules in the biohybrid vesicles maintain most of the activities. This research paves a new way for the synthesis of functional biohybrid structures, and the materials can be used as protein carriers.

Abstract
Single-chain polymer nanoparticles (SCNPs) are protein-inspired materials based on intramolecularly cross-linked polymer chains. We report here the development of SCNPs as uniquely sized nanocarriers that are capable of drug encapsulation independent of the polarity of the employed medium. Synthetic routes are presented for SCNP preparation in both organic and aqueous environments. Importantly, the SCNPs in organic media were successfully rendered water soluble, resulting in two complementary pathways toward water-soluble SCNPs with comparable resultant physicochemical characteristics. The solvatochromic dye Nile red was successfully encapsulated inside the SCNPs following both pathways, enabling probing of the SCNP interior. Moreover, the antibiotic rifampicin was encapsulated in organic medium, the loaded nanocarriers were rendered water soluble, and a controlled release of rifampicin was evidenced. The absence of discernible cytotoxic effects and promising cellular uptake behavior bode well for the application of SCNPs in controlled therapeutics delivery.

Abstract
In recent years, an emerging research area has been the surfactant behavior of polymer-tethered nanoparticles. In this feature article, we have provided a general introduction to the synthesis, self-assembly, and interfacial activity of polymer-tethered inorganic nanoparticles, polymer-tethered organic nanoparticles, and polymer-tethered natural nanoparticles. In addition, applications of the polymer-tethered nanoparticles in colloidal and materials science are briefly reviewed. All research demonstrates that amphiphilic polymer-tethered nanoparticles exhibit surfactant behavior and can be used as elemental building blocks for the fabrication of advanced structures by the self-assembly approach. The polymer-tethered nanoparticles provide new opportunities to engineer materials and biomaterials possessing specific functionality and physical properties.

Abstract
Herein, we report a feasible method to prepare a tadpole-shaped PEG-POSS-(Azo)7 polymer. The polymer self-assembled into a large vesicle in aqueous solution, undergoing reversible smooth-curling transformation responsive to UV and dark conditions. Incorporating POSS units into the azopolymer furnished quick trans-cis isomerization along a cubic orientation. The orientational isomerization formed some pores on the vesicular membrane and endowed the highly sensitive photoresponsive property. Encapsulation of various fluorescent dyes affected the hydrophilic/hydrophobic ratio of self-assemblies, causing their morphological transition from vesicles to micelles. Response to UV irradiation, the quick trans-cis isomerization resulted in rapid release of the encapsulated dyes. The intriguing photoresponsive property renders this kind of tadpole-shaped POSS hybrid azopolymer a potential for application in controlled release of drug.

Abstract
We report the preparation and self-assembly of amphiphilic hybrid nano building blocks (NBBs) with surfactant-mimicking structures. These NBBs, composed of hydrophilic silica-like heads tethered with well-defined one or two hydrophobic polystyrene (PS) tails, were prepared by efficient intramolecular cross-linking via silane chemistry. Using a series of "AB" diblock copolymers (BCPs) and "ABA" tri-BCPs of PS and poly(tert-butyl acrylate-co-3-(trimethoxysilyl)propyl methacrylate) (P(tBA-co-TMSPMA)), the intramolecular self-folding of P(tBA-co-TMSPMA) blocks and the deprotection of tert-butyl groups were demonstrated to be an efficient method to prepare amphiphilic NBBs with a hydrophilic silica head tethered by one or two PS tails. The formation of NBBs was carefully studied by gel permeation chromatography, nuclear magnetic resonance spectroscopy, and transmission electron microscopy. The self-assembly of these amphiphilic NBBs was further investigated by fixing the molecular weight of PS tails and varying the size of hydrophilic heads. The intramolecular cross-linking of hydrophilic heads that shifted the hydrophilic/hydrophobic balance of polymers resulted in morphological transitions from bilayered vesicles to spherical micelles. Spherical micelles prepared from NBBs with large hydrophilic heads were found to have surface protrusions that differed from the self-assembly of linear BCPs. We also observed that the chain conformation of PS tails was critical for the self-assembly of NBBs, where the bitailed NBBs with highly stretched PS tails favored bilayered vesicle structures.
