title: Photochromism of a water-soluble vesicular [2.2]paracyclophane-bridged imidazole dimer.
abstract: Here we report the first photochromism of a newly designed [2.2]paracyclophane-bridged imidazole dimer in water. The photochromic dye with a hydrophilic and a hydrophobic substituent forms vesicles in water and shows instantaneous colouration upon UV light irradiation and successive rapid fading in the dark.
