Cationic and radical polymerization using a boron–thienothiophene–triphenylamine based D–π–A type photosensitizer under white LED irradiation

Abstract

A D–π–A type pull–push photosensitizer, possessing thieno[3,2-b]thiophene, triphenylamine and boron units, was synthesized and used in both free-radical and cationic photopolymerization using DPI salt under white light irritation.
