Abstract

Abstract : The curing of dental materials is one of the important applications of visible‐light photopolymerization. Within this work, tetrakis(2, 4, 6‐trimethylbenzoyl)silane is synthesized and characterized relating to its photochemical properties and its possible usage as a Type I photoinitiator. Abstract : Visible light curing of photopolymers has gained increasing interest in recent years. Dental materials are one of the important areas of application, where the bimolecular camphorquinone/amine initiator system is currently state of the art initiator. In this study, the authors describe the synthesis and photochemistry of tetrakis(2, 4, 6‐trimethylbenzoyl)silane, as cleavable Type I visible light photoinitiator. Besides excellent photobleaching behavior, this photoinitiator can well compete with up to now used long wavelength initiators.
