Abstract
Thiol chemistry is a type of highly efficient chemical reaction between thiols and functional groups. During the past two decades, thiol chemistry has been widely applied in the synthesis and modification of polymers. With the rapid development of polymer chemistry and materials science, more thiol click reactions, which can be efficiently performed under mild conditions, are required. In this research, the synthesis and modification of polymers by thiol-phenylsulfone substitution reactions are reported. A monomer containing two phenylsulfonyl groups is synthesized and the monomer is reacted with bisthiols under mild conditions, leading to the synthesis of novel polymers. Size exclusion chromatography, 1H NMR and differential scanning calorimetry results demonstrate the step-growth polymerization of the monomer. A combination of thiol-phenylsulfone and thiol-disulfide reactions are used in the post-polymerization modification.

Abstract
In contrast to natural polymers, which have existed for billions of years, the first well-understood synthetic polymers date back to just over one century ago. Nevertheless, this relatively short period has seen vast progress in synthetic polymer chemistry, which can now afford diverse macromolecules with varying structural complexities. To keep pace with this synthetic progress, there have been commensurate developments in analytical chemistry, where mass spectrometry has emerged as the pre-eminent technique for polymer analysis. This Perspective describes present challenges associated with the mass-spectrometric analysis of synthetic polymers, in particular the desorption, ionization and structural interrogation of high-molar-mass macromolecules, as well as strategies to lower spectral complexity. We critically evaluate recent advances in technology in the context of these challenges and suggest how to push the field beyond its current limitations. In this context, the increasingly important role of high-resolution mass spectrometry is emphasized because of its unrivalled ability to describe unique species within polymer ensembles, rather than to report the average properties of the ensemble.

Abstract
Cross-metathesis (CM), a carbon-carbon bond transformation that features exceptional selectivity, reactivity and tolerance to functionalities, has been extensively investigated in organic chemistry. On the other hand, the use of CM in polymer synthesis is also growing in both scope and breadth, thus offering a wealth of opportunities for introducing a vast range of functionalities into polymer backbone so as to manipulate properties and expand applications. In this review, we propose the concept of "cross-metathesis polymerization" (CMP) referring to polymer synthesis via repetitive CM reaction and summarize emerging strategies for the precision synthesis of aliphatic polyesters via CMP based on the high CM tendency between acrylates and α- olefins. Due to the carbon-carbon bond-forming step-growth polymerization nature, CMP brings a new concept to polyester synthesis. This remarkable polymerization method possesses unique advantages such as mild condition, full conversion, fast kinetics, almost quantitative yield and extraordinary tolerance to functionalities. In particular, CMP provides the ability to regulate macromolecular architectures including linear, block, cyclic, star, graft, dendron, hyperbranched and dendrimer topologies. Ultimately, advanced polymeric materials with outstanding performances can be facially constructed based on these sophisticated macromolecular architectures.

Abstract
Click reactions have provided access to an array of remarkably complex polymer architectures. However, the term "click" is often applied inaccurately to polymer ligation reactions that fail to respect the criteria that typify a true "click" reaction. With the purpose of providing a universal way to benchmark polymer-polymer coupling efficiency at equimolarity and thus evaluate the fulfilment of click criteria, we report a simple one-pot methodology involving the homodicoupling of α-end-functionalized polymers using a small-molecule bifunctional linker. A combination of SEC analysis and chromatogram deconvolution enables straightforward quantification of the coupling efficiency. We subsequently employ this methodology to evaluate an overlooked candidate for the click reaction family: the addition of primary amines to α-tertiary isocyanates (α-(t)NCO). Using our bifunctional linker coupling strategy, we show that the amine-(t)NCO reaction fulfills the criteria for a polymer-polymer click reaction, achieving rapid, chemoselective, and quantitative coupling at room temperature without generating any byproducts. We demonstrate that amine-(t)NCO coupling is faster and more efficient than the more common amine-tertiary active ester coupling under equivalent conditions. Additionally, we show that the α-(t)NCO end group is unprecedentedly stable in aqueous media. Thus, we propose that the amine-(t)NCO ligation is a powerful new click reaction for efficient macromolecular coupling.

Abstract
Three- and four-arm star shaped polymers, as well as diblock copolymers, are synthesized via acyclic diene metathesis (ADMET) polymerization. This is accomplished by using an asymmetric α,ω-diene containing a terminal double bond and an acrylate, which is polymerized in the presence of multifunctional acrylates as selective and irreversible chain transfer agents using Hoveyda-Grubbs second generation catalyst. High cross-metathesis selectivities are achieved at low temperatures enabling good control over molecular weights. Furthermore, additional polyethyleneglycol (PEG) blocks are attached to these polymers via Heck coupling of the acrylate end-groups of these polymers with aryl iodide functionalized PEG, obtaining three- and four-arm star shaped di- and triblock copolymers with molecular weights up to 31 kDa.

Abstract
A novel glucose-sensitive nanogel was conveniently prepared through one-pot thiol-ene copolymerization of pentaerythritol tetra(3-mercaptopropionate), poly(ethylene glycol) diacrylate, methoxyl poly(ethylene glycol) acrylate and N-acryloyl-3-aminophenylboronic acid. The formation of core-shell nanogel was verified by proton nuclear magnetic resonance, dynamic laser scattering (DLS) and transmission electron microscopy. The successful incorporation of phenylboronic acid (PBA) in the nanogel was confirmed through Fourier transform infrared spectroscopy, inductively coupled plasma mass spectrometry and fluorescence technology. Owing to the presence of PBA, the nanogel exhibited high glucose sensitivity in phosphate-buffered saline determined by DLS and fluorescence technology. The increased amount of glucose causes an increase in the hydrodrodynamic radius and a decrease in the fluorescence intensity of PBA-alizarin red S (ARS) complex in the nanogel at pH 7.4 because of the competitive substitution of ARS to form the hydrophilic PBA-glucose complex. ARS and insulin were loaded into this glucose-sensitive nanogel. In vitro release profiles revealed that the drug release from the nanogel could be triggered by the presence of glucose. The more glucose in the release medium, the more drug was released and the faster the release rate. Furthermore, in vitro methyl thiazolyl tetrazolium assay, lactate dehydrogenase assay and hemolysis test suggested that the nanogel was biocompatible. Therefore, the PBA-incorporated nanogel with high glucose-sensitivity and good biocompatibility may have great potential for self-regulated drug release.
