An Organic Optical Transistor Operated under Ambient Conditions

Abstract

It takes three: The key functionalities of an optical transistor, gating and amplification, are demonstrated exploiting the photophysical properties of a molecular triad (see picture). Two building blocks of the triad are highly efficient fluorophores, whereas the third building block is a photochromic molecule that can be reversibly interconverted between two bistable forms by light.
