Red-light-induced cationic photopolymerization: perylene deriva-tives as efficient photoinitiators

Résumé

Nine different perylene derivatives are prepared and their ability to initiate, when combined with an iodonium salt (and optionally N -vinylcarbazole), a ring-opening cationic photopolymerization of epoxides under very soft halogen lamp irradiation is investigated. One of them is particularly effi cient under a red laser diode exposure at 635 nm and belongs now to the very few systems available at this wavelength. The photochemical mechanisms are studied by steady-state photolysis, electron spin resonance spin trapping, fl uorescence, cyclic voltammetry, and laser fl ash photolysis techniques.
