Self assembled monolayer field effect transistors (SAMFETs) are reported using a phenylene‐thiophene containing semiconducting mesogen attached through a trichlorosilane anchoring group. Monolayer films, covalently attached to silicon dioxide substrates, form in less than 10 h from solution, thanks to the accelerated reaction of the trichlorosilane anchor. Devices exhibit mobilities as high as 1.7
据报道,自组装单层场效应晶体管(SAMFET)使用的苯并噻吩含有通过三氯硅烷固定基团连接的半导体液晶元。由于三氯硅烷锚固剂的加速反应,共价附着在二氧化硅基质上的单层薄膜在不到10小时的时间内即可从溶液中形成。器件的迁移率高达1.7×10 -2 cm 2 V -1 s -1,电流高达15μA(开/关电流比为10 6),通道长度最大为10时,器件在大面积上的产率接近统一100微米
