AbstractProblems associated with intrinsically destructive sensing mechanisms of organic field. effect transistors constitute one of the main obstacles to using them for the practical applications in sensing and switching. Here we report a smart system, in which a photochromic spiropyran (SP) combined with polymethyl methacrylate (PMMA) is used as a gate dielectric, to develop functional molecular devices capable of photoswitching their electrical conductivity in a noninvasive manner. Significant and reversible capacitance and current transitions in devices are generally demonstrated experimentally when the SP molecules undergo their documented reversible photoisomerization. This concept of conformation. induced capacitive coupling offers attractive new prospects for the development of functional devices by utilizing other stimuli. responsive molecular materials.
