Among the nanoscale devices, photoinduced molecular switches has opened a challenging research area for applications in the development of gating channels. Azobenzene is an excellent candidate for an optical molecular switch to control mass transport through a membrane due to photoisomerization. Spectroscopic evidence for the photoreorientation of azobenzene determined by the light propagation was presented first by using a film of the amorphous polymer with azobenzene side chains. In this poster, we are representing a realization of an optical molecular switch that acts as a gating channel for reversibly opening and closing ion flow through an azobenzene polyelectrolyte multilayer film deposited layer-by-layer onto nanoporous alumina membrane. The ion flow through the PEM membrane could be reversibly controlled due to the slantwise irradiation of unpolarized light.
