Hydrogen bond complex used as visible light photoinitiating system for free radical photopolymerization: Photobleaching, water solubility

Abstract

Abstract A type II photoinitiator (2E,6E)-2,6-bis((1H-pyrrol-2-yl)methylene)cyclohexan-1-one(BPC) was conveniently synthesized through Claisen-Schmidt reaction. Hydrogen bond complex BFC/TEOA not only exhibits high photo-reactivity on the visible light polymerization, but also shows rapid bleach, excellent dispersibility in water which could be potential for photo-induced organic coating.
