Abstract

A visible light cationic photoinitiating system under chemiluminescence irradiation using sulfonium salt is reported. The visible light emitted from the chemiluminescence reactions, absorbed by the sulfonium salt, essentially leads to the formation of protonic acids capable of initiating cationic polymerization of oxirane and vinyl monomers. The process is suitable for the formation of linear polymer chains as well as cross-linked functional networks with aggregation-induced emission property. Notably, high "post polymerization" efficiency in dark (similar to 20%) was observed, which can compensate the limited chemiluminescence fluorescence efficiency and favors to increase the conversion.
