摘要：

设计并合成了一类新的可用于有机场效应晶体管(OFET)的聚合物半导体材料聚(茚并芴-三苯胺)(pIFTPA1~4), 通过核磁共振谱和凝胶渗透色谱等对聚合物进行了表征, 同时对其场效应薄膜晶体管性能进行了测试. 结果表明, 这些聚合物形成了无定形半导体膜, 在空气中稳定, 其载流子迁移率远高于聚三苯胺(pTPA)类材料, 其中pIFTPA1载流子迁移率高达4×10-2 cm2/(V·s), 开关比为106.

Abstract:

Novel materials for organic field effect transistor——poly(indenofluorene-triphenylamine)(pIFTPA1—4) were synthesized and characterized by NMR and gel permeation chromatography(GPC). The organic field effect transistors(OFETs) based on these polymers were investigated. It was observed that stable amorphous thin films were formed in the devices, with better charge-carrier mobility than poly(triphenyl-amine)(pTPA). In four polymers synthesized, pIFTPA4 presents the highest hole mobility, as high as 4×10-2 cm2/(V·s), with an ON/OFF ratio in excess of 106.
