Abstract

The invention discloses bis(benzothiophene) ethylene polymers and a preparation method and application thereof. The polymers have a structural formula I or I' shown in the specification, wherein R is C1-C60 straight-chain or branched-chain alkyl. The invention further discloses a preparation method of the polymers. The synthesis route of the method is simple and effective; the raw materials are commercialized cheap products, thereby ensuring low synthesis cost; the synthesis method has universality and can be popularized in the synthesis of polymers based on bis(benzothiophene) ethylene compounds through substitution with various substituent groups. The migration rate and switch ratio of PFET prepared by using the polymers based on bis(benzothiophene) ethylene compounds as an organic semiconductor layer are relatively high, wherein the migration rate can be 5.79cm<2>V<-1>s<-1> at most and the switch ratio is larger than 10<6>; the polymers have a good application prospect to PFET devices.
