摘要

This study presents 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) as an innovative photoinitiator for visible-light-driven polymerization of a range of vinyl monomers under 400 nm LED illumination. The use of DDQ is essential because its high oxidative potential and visible-light absorption enable the efficient generation of initiating radicals under mild conditions, ensuring broad monomer compatibility and controlled polymer growth.Using DDQ, we efficiently polymerized monomers including acrylamide, N-isopropyl acrylamide, acrylic acid, styrene, methyl methacrylate, methyl acrylate, ethyl methacrylate, as well as their copolymers. Polymerization performance was assessed on a 5 mmol scale, achieving notable conversion rates. Our results indicate that DDQ’s photoinitiation efficacy depends on both the light wavelength and its concentration. The broad applicability of DDQ renders it a cost-effective alternative to conventional photoinitiators for synthesizing diverse polymer materials. Structural analyses by NMR, FT-IR and TGA confirmed successful polymer formation. These findings pave the way for sustainable polymerization strategies with promising applications in materials science and biomedicine.
