Description

General description

Benzophenone is an aromatic carbonyl compound. Photoinitiated free radical polymerization of benzophenone in the presence of N-methyldiethanolamine as a coinitiator has been reported.[1] Polymeric benzophenone photoinitiator (PBP) has been synthesized by using “Thiol-ene Click Chemistry” and characterized by ¹H NMR, FTIR, UV, and phosphorescence spectroscopies.[2]

Application

Benzophenone is suitable anchoring agent used for the surface modification of graphene.[3] It may be used in the preparation of N-(diphenylmethylene)-N′-(tert-butoxycarbonyl)-N′- (4-bromophenyl)-p-phenylenediamine.[4]
