Dendritic cyclotriphosphazene derivative with hexaxis(alkylazobenzene)substitution as photosensitive trigger

摘要

A dendritic cyclotriphosphazene derivative was synthesized by substitution with six alkylazobenzenes onto cyclotriphosphazene.Photo-induced trans-to-cis isomerization of the azobenzene moieties was discussed on each substituent.It was also investigated that the dendrimer acted as a photosensitive trigger for microenvironmental modification of chirally self-assembled organogels through the isomerization.
