The π-conjugated polymer, PQBOC8 , can be easily assembled into a large-area crystalline ultrathin film at the CHCl 3 /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 lo...

Summary:The π-conjugated polymer, PQBOC8 , can be easily assembled into a large-area crystalline ultrathin film at the CHCl 3 /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. An ultrathin crystalline polymer film was prepared using a novel solution-phase self-assembled method and exhibited high performance in phototransistor devices.
