Photosensitive Pentacene Precursor: Synthesis, Photothermal Patterning, and Application in Thin-Film Transistors



The Diels–Alder adduct of pentacene and N-sulfinylmethacrylamide is used as a soluble, photopolymerizable precursor of pentacene for fabrication of patterned thin-film transitors. The Figure shows the optical micrograph of patterned pentacene derived from the exposure of this adduct to UV radiation, followed by development in methanol and annealing at 200 °C for 90 s.
