Self-Contained Photoacid Generator Triggered by Photocyclization of Triangle Terarylene Backbone
We herein propose a new type of efficient neutral photoacid generator. A photoinduced 6pi-electrocyclization reaction of photochromic triangle terarylenes triggers subsequent release of a Br¡ãnsted acid, which took place from the photocyclized form. A H-atom and its conjugate base were introduced at both sides of a 6pi-system to form the self-contained photoacid generator. UV irradiation to the 6pi-system produces a cyclohexa-1,3-diene part with a H-atom and a conjugate base on the sp3 C-atoms at 5- and 6-positions, respectively, which spontaneously release an acid molecule quantitatively forming a polyaromatic compound. A net quantum yield of photoacid generation as high as 0.52 under ambient conditions and a photoinitiated cationic polymerization of an epoxy monomer are demonstrated.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.6287-82-7. In my other articles, you can also check out more blogs about 6287-82-7
