WebGenerally, cationic photopolymerization is initiated by photoacid generators ( PAGs ), which liberate carbo-cations and protons upon a light stimulus. Although there also exist non-ionic PAG s, the onium salts, introduced by Crivello in the 1970s, 6 represent the most efficient cationic photoinitiators to date. WebMay 20, 2015 · We herein propose a new type of efficient neutral photoacid generator. A photoinduced 6π-electrocyclization reaction of photochromic triangle terarylenes triggers subsequent release of a Brønsted acid, which took place from the photocyclized form. A H-atom and its conjugate base were introduced at both sides of a 6π-system to form the …

Webacid, formed by the initiator, continues the polymerization also in the absence of light. As disadvantages one must mention the inhibition by bases, and chain transfer resulting from impurities of water. Still the cationic photo-polymerization is a niche technique compared to the omni-present free radical photopolymerization moreover due to the toking definitionWebplatforms. A critical component of photoresist formulations is the photo-acid generator or PAG. PAGs are the photoactive ingredient in photoresists that produce acid upon irradiation. This acid subsequently serves to catalyze deprotection of the polymeric resist or initiate cationic polymerization or curing of monomeric groups; generically tokiniandy.comWebOur photo acid generator product line has proven quality and performance for excimer resist applications with industry leading resist manufactures.
