We report an aqueous and near-infrared (NIR) light mediated photoinduced reversible addition-fragmentation chain transfer (photo-RAFT) polymerization system catalyzed by tetrasulfonated zinc phthalocyanine (ZnPcS4- ) in the presence of peroxides. Taking advantage its fast rates high oxygen tolerance, this is successfully applied for preparation hydrogels. Exploiting enhanced penetration NIR light, gelation effectively performed through non-transparent biological barriers. Notably, RAFT agents embedded these hydrogel networks can be reactivated on-demand, enabling healing under irradiation. In contrast to minimal capability (<15 %) hydrogels prepared free radical (FRP), RAFT-mediated display more than 80 % recovery tensile strength. Although healable polymer UV blue lights have already been established, work first photochemistry using facilitating thick

Abstract Polymerization‐induced self‐assembly (PISA) combines polymerization and in situ of block copolymers one system has become a widely used method to prepare copolymer nanoparticles at high concentrations. The persistence polymers the environment poses huge threat ecosystem represents significant waste resources. There is an urgent need develop novel chemical approaches synthesize degradable polymers. To meet with this demand, it crucial install degradability into PISA nanoparticles. Most recently, have been synthesized by introducing degradation mechanisms either shell‐forming or core‐forming blocks. This Minireview summarizes development PISA, including shell‐degradable, core‐degradable, all‐degradable Future will benefit from expansion techniques new adaptation high‐throughput for both syntheses studies.

Abstract Reversible addition–fragmentation chain transfer polymerization (RAFT) is a popular method for the synthesis of well‐defined macromolecules, but its sensitivity to oxygen major limitation many industrial applications. Recent research has focused on developing strategies confer tolerance onto RAFT polymerization, eliminating need deoxygenation steps and allowing simpler reaction conditions. This minireview highlights several promising approaches achieve in including enzyme‐mediated, alkylborane‐initiated, photomediated methods. The potential applications oxygen‐tolerant are also discussed, demonstrating promise significant advances large‐scale polymer synthesis.

Organocatalyzed reversible-deactivation radical polymerizations (RDRPs) are attractive for many applications. Here, we developed photoredox-mediated RDRP by activating (hetero)aryl sulfonyl chloride (ArSO2 Cl) initiators with pyridines and designing a novel bis(phenothiazine)arene catalyst. The in situ formed pyridinium intermediates effectively promote controlled chain-growth from ArSO2 Cl, enabling access to various well-defined polymers high initiation efficiencies dispersities under mild conditions. This versatile method allows "ON/OFF" temporal control, chain-extension, facile synthesis of different polymer brushes via organocatalyzed grafting reactions linear chains. Time-resolved fluorescence decay studies calculations support the reaction mechanism. work provides transition-metal-free tailor readily available aromatic initiators, will design polymerization leveraged photoredox catalysis.

Abstract The synthesis of polymers with high molecular weights, controlled sequence, and tunable dispersities remains a challenge. A simple effective visible‐light photoiniferter reversible addition‐fragmentation chain transfer (RAFT) polymerization is reported here to realize this goal. Key strategy the use switchable RAFT agents (SRAs) tune activities coupled inherent highly living nature polymerization. SRAs were in situ adjusted by addition acid. In chain‐transfer coefficient, photolysis kinetic studies revealed that neutral protonated showed different rates, which unique terms dispersity control. This features no catalyst, exogenous radical source, temporal regulation visible light, unprecedented weight regime (up 500 kg mol −1 ). Pentablock copolymers three combinations also synthesized, highlighting was maintained even for blocks large dispersities. T g lowered high‐dispersity similar MWs due existence more low‐MW polymers. holds great potential advanced materials weight, sequence.
