DOI: 10.1002/adfm.202000761
Abstract: Due to their selective crosslinking chemistry and well‐defined mechano‐biochemical characteristics, hydrogels crosslinked by thiol‐Michael addition reactions have garnered immense interest for 3D cell culture applications. These hydrogels are typically formed via end‐linking of bis‐cysteine oligopeptides… read more here.

DOI: 10.1002/marc.202100070
Abstract: Covalent adaptable networks (CANs) based on the thiol-Michael (TM) linkages can be thermal and pH responsive. Here, a new vinyl-sulfone-based thiol-Michael crosslinker is synthesized and incorporated into acrylate-based CANs to achieve stable materials with dynamic… read more here.

DOI: 10.1021/acsmacrolett.8b00435
Abstract: In this contribution, three o-nitrobenzyl-based photobase systems were synthesized and evaluated for visible light initiated thiol-Michael addition polymerizations. With a modified structure, the (3,4-methylenedioxy-6-nitrophenyl)-propyloxycarbonyl (MNPPOC) protected base performance exceeds that of the nonsubstituted 2-(2-nitrophenyl)-propyloxycarbonyl (NPPOC)… read more here.

DOI: 10.1021/jacs.2c03525
Abstract: The development of photopolymers that can be depolymerized and subsequently re-cured using the same light stimulus presents a significant technical challenge. A bio-sourced terpenoid structure, l-carvone, inspired the creation of a re-curable photopolymer in which… read more here.

DOI: 10.1039/c7py01356f
Abstract: Thiol-maleimide adducts have been used as dynamic crosslinkers to form soft, elastic, and stimuli responsive polymeric materials. Thiol-Michael adducts can undergo dynamic exchange at elevated temperature or elevated pH values. Due to the dynamic behaviour… read more here.

DOI: 10.1039/c7py02052j
Abstract: Dimethylphenylphosphine was used to efficiently initiate the thiol-Michael addition polymerization to yield 5-hydroxymethylfurfural (HMF) derivative based poly(β-thioether esters) with relatively high molecular weights (over 10 000 g mol−1) under mild conditions. The synthesized linear polymers with… read more here.

Abstract: We present a thermally initiated thiol-Michael reaction based on initiation via the temperature-dependent thiol-TEMPO oxidation-reduction reaction. In the presence of a thiol, 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO, pK a = 5.5) is reduced to produce a much stronger… read more here.

DOI: 10.1039/d1py00198a
Abstract: Interpenetrating networks (IPN) comprise two or more networks which are woven but not covalently bonded to each other. This is in contrast to simple, or single Networks (SN), which contain only one network that is… read more here.
