Large scale synthesis of dendrimers to apply to multifunctional nano materials

Large scale synthesis of monodispersed dendrimers were established to give polyol and polyacrylate dendrimers in 100 gram scales.Photofunctuinal dendrimers with terminal photopolymerization and/or photocrosslinking units were conveniently prepared by chemical midification at the dendrimer surfaces in one steps. These types of dendrimers exhibited quite characteristic photochemical behaviors and extraordinary high photoreactivity.We also examined the other type of teriminal modification based on physical adsorption. It was found that the polypyridyl dendrimers were self-organized into the hydrogen-bonded globular assemblages by mixing with the desired photoresponse carboxylic acids derivatives to exhibit specific photofunctionalities depending on the dendrimer generations.
