A layer of functionalized disperse red 19 (DR19) chromophore molecules leads to novel reversible photoelectrical characteristics in organic thin film field effect transistor. Photoassisted poling, along with the change in the dipole of the DR19 under illumination, and photoinduced charge transfer to electron traps in the DR19 layer combine to change the threshold voltage of transistors by up to 100 V.
