Abstract
Recent progress in photochemical generation of organic bases and its applications to polymer science and technologies are reviewed. Although photobase generators (PBGs) have been desired as a novel photolatent catalyst, fewer examples are known compared to photoradical and photoacid generators. In this decade, several PBGs such as carbamates, O-acyloximes, and ammonium salts have been improved in thermal stability, solubility, multi-functionality, and photo-sensitivity. In addition, new molecular designs including amineimides, α-aminoketones, some amidine precursors, and aromatic ureas have been proposed as novel PBGs. New applications of these PBGs have been developed in photo-induced polymerization, depolymerization, crosslinking, and de-crosslinking as well as photo-imaging.
