Abstract

A zwitterionic gemini surfactant containing a photoactive azobenzene chromophore forms vesicles in aqueous solution only from a photostationary state containing a majority of the Z-isomer (26:74 E:Z). These vesicles are stable in the dark over several weeks, trapping the azobenzene in the Z form. Compared to an analogous system based on a cationic azobenzene gemini surfactant forming vesicles with the E- but not the Z- isomer, the new system displays significantly enhanced photosensitivity towards light-induced lysis of the vesicles.
