title: A self-assembled ultrathin crystalline polymer film for high performance phototransistors.
abstract: The π-conjugated polymer, PQBOC8, can be easily assembled into a large-area crystalline ultrathin film at the CHCl3/water interface. A phototransistor based on this ultrathin film showed a large photoresponsivity of 970 A W(-1), and a photocurrent/dark current ratio of 1.36 × 10(4) under a very low white light irradiation.
