Summary: In this study, a series of new cross-linked polysiloxane polymers were successfully prepared by UV-induced hydrothiolation click-reaction using functionalized cyclo- and oligosiloxane precursors. The physico-mechanical properties of these polymers were investigated, showing that their mechanical properties and thermal stability can be fine-tuned by changing the structure of the initial vinyl precursor.

Summary: Daylight-activated detoxifying nanofibrous membranes efficiently detoxify 1,3-dichloropropene (1,3-D) through a thiol-ene click reaction under daylight irradiation. The detoxification process is initiated and sustained by light-induced cascade chemical attacks of thiyl radicals, showing rapid and massive detoxification effects. These membranes also demonstrate a detoxification tailing effect in the absence of light sources, making them effective for personal protective equipment.

Summary: A green and sustainable strategy is developed for the synthesis of methacrylic monomers and polymer networks using biobased eugenol. The properties of these biobased polymer networks can be tuned by changing the types of eugenol-based monomers and thiol crosslinkers. These networks can be chemically degraded into carboxylic acids and thermally degraded into CO and CO2, offering a pathway to degradable sustainable polymers and materials.

Summary: This study investigates the modification of cellulose and lignin through esterification, resulting in olefin-functionalized ethyl cellulose and lignin. These derivatives are then used to prepare cellulose and lignin cross-linker polymers via thiol-ene click chemistry. The concentration of olefin group in the derivatives reaches 2.8096 mmol/g and 3.7000 mmol/g respectively, and the tensile stress at break of the cellulose cross-linked polymers is 23.59 MPa. The presence of ester groups and degradation products improves thermal stability. The research is significant for the chemical modification and practical application of lignin and cellulose.

Summary: In this study, a green and simple modification approach to prepare highly dispersible functionalized graphene via thermal thiol-ene click reaction was successfully demonstrated. The functionalized graphene showed high atomic content of S and various functional groups on the surface, as confirmed by Raman spectroscopy. The direct attachment of multifunctional groups on the surface of pristine graphene is highly demanded for various applications such as graphene ink formulations, coatings, and supercapacitors.

Summary: This study demonstrates the significant role of thiyl radicals produced by thiol oxidation in driving the spontaneous thiol-ene polymerization in the absence of solvents, heating, and intentional radical formation. Factors influencing reactivity, kinetics, solvation of thiols, and nature of initiating radicals were studied through various techniques, showing that the polarization of S-H bond drives thiol air oxidation. Thiols with electron-withdrawing substituents and hydrogen-bonded thiol-solvent (or thiol-alkene) complexes promote self-initiation by increasing S-H bond polarization.

Summary: The thiol-ene 'click' reaction is a versatile process for carbon-sulfur bond formation with widespread applications in synthetic biology and beyond. Thioesters are key intermediates in various processes, and efficient methods for their synthesis are of great interest. Acyl-thiol-ene (ATE) has been successfully used for the synthesis of biomolecular thioesters, demonstrating the significant impact of amino acid side chains on the reaction outcomes. Additionally, radical generated thioesters can undergo efficient S-to-N acyl transfer and desulfurisation to provide 'sulfur-free' ligation products, with diverse applications in chemical ligation and bioconjugation.

Summary: Thiol-ene/yne click reactions were catalyzed by anisotropic 1D Bi2S3 nanorods under visible light irradiation, achieving excellent product yields and high tolerance to various substrates. Mechanistic studies supported the role of photoexcited holes in the formation of thiyl radicals. The methodology allowed for gram-scale synthesis of benzyl styryl sulfide with a chemical yield of 90%, and the nanorods exhibited stability and favorable photocatalytic activity throughout multiple reaction cycles.

Summary: Various acylates and phenylcarbamates of (ethyl)cellulose were synthesized by modifying the residual hydroxyls of ethyl DS = 2.50 EC. Chiral nematic mesophases in different solvents were studied, showing a right-handed structure with DCA and an inversion of twist sense with AA and chloroform as acyl (or phenylcarbamoyl) substitution increased. Temperature elevation was found to strengthen a left-handed twisting power in each chiral nematic mesophase, with reversal of twist handedness observed in some cases.

Summary: This paper presents a microbial approach to fabricate biomimetic composites that mimic natural wood. The researchers focused on the chemical composition of woody biomass and used bacterial cellulose imbued in modified cationic lignin for in situ bioprocessing. The resulting composites exhibited enhanced thermal stability and crystallinity, as well as comparable tensile properties and specific strength to heavy wood species under hydrated conditions.
