Abstract
Photoinitiated polymerization and cross-linking reactions form the basis of numerous applications in the coatings, reprographic, and microelectronics industries.1–5 Nearly all of the commercially significant photoinitiators are organic compounds that generate free radicals and/or strong acids upon exposure to light.5–8 Common examples include benzoin and its derivatives, benzil ketals, acetophenone derivatives, aromatic ketone/amine combinations, and onium salts belonging to the diaryliodonium, triarylsulfonium, and triarylseleonium families. Despite a substantial number of studies exploring the potential of inorganic and organometallic coordination complexes as photoinitiators, these systems have yet to gain widespread acceptance. Several factors contributing to this dominance of the photoinitiator market by organic compounds can be cited: (1) no compelling case had been made that inorganic and organometallic complexes that generate free radicals offer significant advantages over the traditional organic free radical sources, (2) the facile production of strong Brønsted or Lewis acids via the photodecomposition of onium salts had no counterpart among inorganic and organometallic complexes, and (3) electronic structure-reactivity relationships and other fundamental concepts needed to understand the primary photochemical processes in photoinitiator systems were more advanced for organic compounds.
