Recently, the mechanism of visual information processing has been intensively studied at the molecular level. The application of such biological functions will lead to the development of models for new functional devices. In this study, we prepared an artificial molecular membrane model, which has a similar function to the retina, for the first time. A feature of the model is the conversion of light information to electrical oscillation signals through structural changes of the membrane initiated by a photochemical reaction. This model is expected to be useful in such applications as parallel information processing, etc.
