Light-driven photochromism-induced reversible switching in P3HT–spiropyran hybrid transistors

Abstract

We demonstrate the use of P3HT–spiropyran blends as an active layer to achieve reversible photoswitching effects in solution-processed organic field-effect transistors (OFETs). Conformational changes of spiropyrans triggered by light with different wavelengths produce two distinct interaction strengths at organic/organic interfaces that can reversibly modulate the channel conductance of OFETs in a noninvasive manner. This concept of organic–organic interfacial modification offers attractive new prospects for the development of organic electronic devices with desired properties.
