Abstract
The utilization of polymer conformations to construct a variety of superlattices is a common method within the field. However, this technique often results in only long-range ordering rather than the formation of distinct superlattices. In this study, a well-organized array of discrete pancake-shaped superlattices (DPSs) is successfully obtained through the utilization of air-liquid interface self-assembly, facilitated by the confined environment created by a block copolymer. It is crucial to note that both the self-assembly behavior and resulting morphologies of the DPSs can be precisely tuned by adjusting several experimental parameters, most notably the concentration and molecular architecture of the block copolymers. Furthermore, this work provides valuable insights into the formation processes and mechanisms underpinning the DPSs. The approach described here is both straightforward and efficacious, establishing a strong foundation for subsequent research and the development of non-close-packed superlattice structures.

Abstract
Mechanochemistry can lead to the degradation of the properties of covalent macromolecules. In recent years, numerous functional materials have been developed based on block copolymers (BCPs), however, like homopolymers, their chains could undergo mechanochemical damage during processing, which could have crucial impact on their performance. To investigate the mechanochemical response of BCPs, multiple polymers comprising different ratios of butyl acrylate and methyl methacrylate were prepared with similar degree of polymerization and stressed in solution via ultrasonication. Interestingly, all BCPs, regardless of the amount of the methacrylate monomer, presented a mechanochemistry rate constant similar to that of the methacrylate homopolymer, while a random copolymer reacted like the acrylate homopolymer. Size-exclusion chromatography showed that, in addition to the typical main peak shift towards higher retention times, a different daughter fragment was produced indicating a secondary selective scission site, situated around the covalent connection between the two blocks. Molecular dynamics modeling using acrylate and methacrylate oligomers were carried out and indicated that dynamic phase separation occurs even in a good solvent. Such non-random conformations can explain the faster polymer mechanochemistry. Moreover, the dynamic model for end-to-end chain overstretching supports bond scission which is not necessarily chain-centered.

Abstract
Polymer mechanochemistry is a promising technology to convert mechanical energy into chemical functionality by breaking covalent and supramolecular bonds site-selectively. Yet, the mechanochemical reaction rates of covalent bonds in typically used ultrasonication setups lead to reasonable conversions only after comparably long sonication times. This can be accelerated by either increasing the reactivity of the mechanoresponsive moiety or by modifying the encompassing polymer topology. Here, a microbubble system with a tailored polymer shell consisting of an N2 gas core and a mechanoresponsive disulfide-containing polymer network is presented. It is found that the mechanochemical activation of the disulfides is greatly accelerated using these microbubbles compared to commensurate solid core particles or capsules filled with liquid. Aided by computational simulations, it is found that low shell thickness, low shell stiffness and crosslink density, and a size-dependent eigenfrequency close to the used ultrasound frequency maximize the mechanochemical yield over the course of the sonication process.

Abstract
Block copolymers (BCPs) are used in numerous applications in modern materials science. Yet, like homopolymers, BCPs can undergo covalent bond scission when mechanically stressed (mechanochemistry), which could lead to unexpected consequences in such applications. BCPs' heterogeneity may affect force transduction, perhaps changing force distribution and localization. To verify this, a gem-dichlorocyclopropane (gDCC) embedded linear chain is prepared and extended with a poly(methyl methacrylate) block. When stressed in solution, the mechanochemical ring-opening of gDCC is accelerated compared to homopolymers, even though the mechanophores are at the chain ends. Moreover, a higher mechanophore activation selectivity is obtained. These results indicate that mechanochemical response outside, and even far from the chain center is quite prominent in BCPs, and that forces along the polymer chain can efficiently activate multi-mechanophores regions, even when far from the polymer midchain.

Abstract
Mechanical force as a type of stimuli for smart materials has obtained much attention in the past decade. Color-changing materials in response to mechanical stimuli have shown great potential in the applications such as sensors and displays. Mechanochromophore-linked polymeric materials, which are a growing sub-class of these materials, are discussed in detail in this review. Two main types of mechanochromophores which exhibit visible color change, summarized herein, involve either isomerization or radical generation mechanisms. This review focuses on their synthesis and incorporation into polymer matrices, the type of mechanical force used, factors affecting the mechanochromic properties, and their applications.

Abstract
The force response of nanosized vesicles shows substantial applications in drug delivery, cancer therapies, and so on. Conventional methods in mechanical studies on vesicles rely on a camera and an optical microscope, which can hardly work for nanosized particles. Herein, we use self-assembled polydiacetylene (PDA) as a chromic mechanoresponsive group to study the responsiveness of nanovesicles under sonication. The sonication-induced deformation of the PDA backbone and reduction in its conjugation length leads to a color transition from blue to red. Three internal and external factors, including greater shear stress, lower polymerization degree, and higher viscosity of the continue phase, have been found to promote the mechanochromism of the vesicles. These results, for the first time, reveal that the force response of vesicles depends on the actual capillary number (correlated with the three explored factors), even at the nanoscale level, which opens a new avenue to mechanical modulation of nanovesicles for the development of vesicle-based bio- and nanotechniques.

Abstract
Traditional chemotherapy suffers from severe toxicity and side effects that limit its maximum application in cancer therapy. To overcome this challenge, an ideal treatment strategy would be to selectively control the release or regulate the activity of drugs to minimize the undesirable toxicity. Recently, ultrasound (US)-responsive drug delivery systems (DDSs) have attracted significant attention due to the non-invasiveness, high tissue penetration depth, and spatiotemporal controllability of US. Moreover, the US-induced mechanical force has been proven to be a robust method to site-selectively rearrange or cleave bonds in mechanochemistry. This review describes the US-activated DDSs from the fundamental basics and aims to present a comprehensive summary of the current understanding of US-responsive DDSs for controlled drug release and drug activation. First, we summarize the typical mechanisms for US-responsive drug release and drug activation. Second, the main factors affecting the ultrasonic responsiveness of drug carriers are outlined. Furthermore, representative examples of US-controlled drug release and drug activation are discussed, emphasizing their novelty and design principles. Finally, the challenges and an outlook on this promising therapeutic strategy are discussed.

Abstract
Smart materials responsible to external stimuli such as temperature, pH, solvents, light, redox agents, and mechanical or electric/magnetic field, have drawn considerable attention recently. Herein, we described a novel rhodamine (Rh) mechanophore-based mechanoresponsive micellar hydrogel with excellent mechanochromic and mechanofluorescent properties. We found with astonishment that, due to the favorable activation of rhodamine spirolactam in the presence of water, together with the stress concentration effect, the mechanoresponsive sensitivity of this hydrogel was enhanced significantly. As a result, the stress needed to trigger the mechanochromic property of Rh in the hydrogel was much lower than in its native polymer matrix reported before. The hydrogel based on Rh, therefore, exhibited excellent mechanochromic property even at lower stress. Moreover, due to the reversibility of color on/off, the hydrogel based on Rh could be used as a reusable and erasable material for color printing/writing. Of peculiar importance is that the hydrogel could emit highly bright fluorescence under sufficient stress or strain. This suggested that the stress/strain of hydrogel could be detected quantificationally and effectively by the fluorescence data. We also found that the hydrogel could respond to acid/alkali and exhibited outstanding properties of acidichromism and acidifluorochromism. Up to now, hydrogels with such excellent mechanochromic and mechanofluorescent properties have rarely been reported. Our efforts may be essentially beneficial to the design of the mechanochromic and mechanofluorescent hydrogels with enhanced mechanoresponsive sensitivity, fostering their potential applications in a number of fields such as damage or stress/strain detection.

Abstract
The fabrication of reactive aggregation nanomaterials through assemblies in a facile and cost-effective manner is much desired but remains to be well explored. Here we show that exquisite and ultra-long (>2 μm) hybrid polymer nanorods (NRs) can be formed by a simple self-assembly of a phenylboronic acid modified genistein crosslinker (Ge-di(HMPBA-pin)) and d-α-tocopheryl polyethylene glycol 1000 (TPGS). The obtained NRs exhibit quantitative and sensitive colorimetric detection of H2O2 with a remarkable detection limit for different stromal materials. More significantly, the presence of H2O2 triggers a distinct morphological transformation of the polymer NR assembly into the secondary structure of micelles via the oxidative deboronation of boronate moieties in HMPBA-pin-SA. It spontaneously induces the aggregation of metal nanoparticles (Au NPs), metal nanorods (Au NRs), quantum dots (MoS2 QDs), metal ions (Cu2+), protein (ferritin) and tetraphenylethene (TPE) molecules, giving rise to a dramatic stimuli-triggered open/close switchable complexation and apparent colorimetric transitions in vitro. This study, for the first time, showcases the fascinating advantages of such unprecedented secondary structure-induced aggregation and uncovers the immense potential to design a plethora of other sensing systems by virtue of the alternate trigger-specific, sacrifice-aggregated building moieties.

Abstract
Optical reporting of covalent bond scission in self-assembled structures in water is an important step toward the detection of forces in biological systems. Here we show that micelles of a diblock copolymer comprising hydrophobic poly(butyl acrylate) and hydrophilic poly(acrylic acid) blocks connected by an off-center mechanoresponsive moiety are mechanochemically active when sonicated in aqueous solution. Facile optical read-out of the force-activation is warranted by formation of a blue-fluorescent anthracene cleavage from the mechanophore, an anthracene-maleimide Diels-Alder adduct. In contrast to the efficient bond scission when the block copolymers are noncovalently anchored in liquid-like micellar cores, isolated unimers in solution are not activated by ultrasonication because the dimensions and viscous drag are drastically lower. These results demonstrate that covalent mechanochemistry can be enabled by noncovalent interactions.
