| Abstract: | Two copolymers of P1 and P2 comprising benzothiadiazole,1,4-bis(dodecyloxy)-benzene units were synthesized by Sonogashira coupling polymerization based on ethynyl-linked 1,2,5,6-naphthalenediimide.Their thermal,optical,electrochemical as well as charge transport properties were studied.Bottom-gate top-contact organic field-effect transistors (OFETs) measurements of P1 and P2 thin films showed different charge transport behaviors.P1 displayed pure electron transport behaviors in OFETs with electron mobility up to 10-3 cm2.V 1·s 1,while P2 exhibited hole transport features.The molecular structure analysis revealed that the structure of P1 has the acceptor-linker-acceptor'(A-L-A') characteristic,and P2 possesses the donor-linker-acceptor (D-L-A) structure feature.The results demonstrate that different molecular structures lead them to have distinct charge transport behaviors.In particular,the first pure electron transport copolymer in OFETs based on 1,2,5,6-naphthalenediimide is achieved. |
