— Photoresponsive artificial membranes have been prepared by embedding amphiphatic alkyl‐ammonium salts containing azobenzene chromophore in dipalmitoylphosphatidylcholine liposomes. The configurational change due to trans→cis photoisomerization of the azobenzene chromophore provided the perturbation of the membrane structure to result in the increase of the water and bromo‐thymol blue permeability of the liposomal membranes.
