제목 Light-Driven Supramolecular Transforamtion and Controlled Release Characteristics of Self-Assemblies of Amide Dendrons
초록 We demonstrated that the self-assembly of the amide dendrons with photoresponsive focal functionality provides an efficient route to stimuli-responsive supramolecular materials. Dendrons with photoresponsive functions respectively formed vesicular structures in aqueous phase. The vesicle of dendron with photocleavable 2-nitrobenzyl ester unit was transformed into a fibrous nanostructure upon exposure to UV irradiation in a basic aqueous solution with concurrent release of entrapped molecules. The vesicle of dendron with the focal azobenzene moiety exhibited photo-controlled behavior in the release of guest molecules from the interior or the membrane of the vesicle. These supramolecular approaches by using dendritic building blocks would provide a unique methodology to construct stimuli-responsive smart materials.
