Efficient PET-RAFT polymerization achieved by using low-toxicity shortwave infrared CuInSe₂/CuInS₂ quantum dots Photoinduced electron/energy transfer reversible addition-fragmentation chain-transfer (PET-RAFT) polymerization enables precise light-controlled polymer growth. Traditional near-infrared strategies often rely on nonlinear optical processes such as two-photon absorption or photon upconversion, which typically require high-intensity laser excitation.
