Ambipolar copolymer of dithienocoronenedi-imide and benzo(bis)thiadiazole with balanced hole and electron mobility
چکیده انگلیسی


• A new copolymer of P(DTCBTZ) containing DTCDI and BTZ has been synthesized.
• The HOMO and LUMO of P(DTCBTZ) are suitable for ambipolar charge transport.
• P(DTCBTZ) showed balanced hole and electron mobility.

A new copolymer P(DTCBTZ) of dithienocoronenediimide (DTCDI) and benzo(bis)thiadiazole (BTZ) as the active layer of organic field-effect transistors (OFETs) is reported. The combination of DTCDI with long alkyl chains and BTZ without alkyl chains results in reduced steric hindrance between acceptors of different polymer backbones. 2,2′-bithiophene is introduced into P(DTCBTZ), and thus donor–acceptor (D–A) interactions are induced. Absorption spectra of solution and thin films of P(DTCBTZ) reveal the existence of relatively strong aggregations of P(DTCBTZ) copolymers in solid state. The new copolymer of P(DTCBTZ) has a HOMO of −5.54 eV and a LUMO of −3.72 eV, which are suitable for both hole and electron transport. Bottom-gate and top-contact (BGTC) transistors were prepared and balanced charge transport was observed, with hole mobility of 0.018 cm2 V−1 s−1 and electron mobility of 0.019 cm2 V−1 s−1, indicating potential for application of polymers containing DTCDI in ambipolar semiconductors.
