Tetrakis(2,4,6‐Trimethylbenzoyl)Silane—A Novel Photoinitiator for Visible Light Curing

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 lo… Show more

“…More interestingly, the similar CQ‐based PIS (CQ/iodonium salt (i.e.,[4‐[octyloxy]phenyl]phenyliodonium hexafluoroantimonate)/EDB) was reported for the polymerization of epoxide under blue light conditions for an additive manufacturing approach (i.e., solution mask liquid lithography) . Recently, an increasing number of novel PISs have been emerging and exhibited high efficiency for free‐radical and/or cationic photopolymerization under visible light . These novel PISs are mainly synthesized with designated chemical structures.…”

“…[2] Dieser Fortschritt wurde besonders durch die Entwicklung von Acylgerman-Initiatoren [3] wie Ivocerin (2)e rleichtert. B. Acylphosphinoxide, [4] Acylsilane, [5] Acylgermane [3] ). Ein Ty p-I-Initiatorsystem, das durch Bestrahlung mit Licht von Wellenlängen über 500 nm gespalten wird und dazu rasches Photobleaching zeigt, wurde bislang noch nicht präsentiert.…”
