Title
Morphology modulation in an azobenzene based supramolecular amphiphiles system
Abstract

Switchable supramolecular amphiphiles based on the host–guest interaction between β-cyclodextrin (β-CD) unit and light-responsive azobenzene derivate (2C12-Azo) have been designed and fabricated. The 2C12-Azo/β-CD supramolecular amphiphile can self-assemble into micro-sized vesicle structure in water at low concentration and exhibit reversible assembly and disassembly behavior upon external UV (365 nm) and visible (435 nm) light irradiation. At high concentration, micro-sized ribbon structure is obtained. Moreover, the morphology of the supramolecular architecture can be further modulated from micro-sized ribbon structure to amorphous film structure by 365 nm light irradiation. It is anticipated that this research will provide further insights into morphology control of supramolecular architecture, and introduce a new way for preparation of upscale smart materials and devices.

Graphical abstractHerein, we demonstrated that the assembly of azobenzene derivate/cyclodextrin supramolecular complex exhibited interesting reversible morphology transition upon external light irradiation.Figure optionsDownload full-size imageDownload as PowerPoint slideHighlights► CD/azobenzene derivatives have been designed as the supramolecular amphiphiles. ► The smart architecture based on above supramolecular amphiphiles is fabricated. ► The morphology transition between vesicles and irregular aggregates is reversible. ► The ribbons can be further modulated to amorphous film upon light-irradiation.
