Electrical and optical properties of Langmuir-Blodgett (LB) films were controlled using photoisomerization of supermolecules having switching, transmission, and working units. Conductivity switching was observed in single-component LB films of the supermolecules on alternate photoirradiation with UV and VIS light. In the mixed LB films with cyanine dye, J-aggregate formation was induced by photoisomerization of the supermolecule. It was suggested that the signal produced by the molecular deformation could be conveyed to the surrounding molecules, causing the cyanine molecules to form J-aggregate.
