摘要:	摘要： A fused aromatic furan‐substituted diketopyrrolopyrrole and novel diphenylfumaronitrile conjugated building blocks are used for the synthesis of an alternating copolymer (DPFN‐DPPF) via Suzuki polycondensation. In this paper, the first attempt to use the diphenylfumaronitrile building block for the synthesis of conjugated polymer is described. The number‐average and weight‐average molecular weights calculated for DPFN‐DPPF are 20 661 and 66 346 g mol−1, respectively. The optical bandgap calculated for DPFN‐DPPF is 1.53 eV whereas the highest occupied molecular orbital (HOMO) value calculated by photoelectron spectroscopy in air (PESA) is 5.50 eV. The calculated HOMO value is lower, which is suitable for stable organic electronic devices. DPFN‐DPPF polymer is used as an active layer in bottom‐contact bottom‐gate organic thin‐film transistor devices and the thin film exhibits a hole mobility of 0.20 cm2 V−1 s−1 in air. Diphenylfumaronitrile‐based alternating copolymer (DPFN‐DPPF) combined with a furan‐substituted diketopyrrolopyrrole‐fused aromatic conjugated building block is reported. DPFN‐DPPF exhibits a band‐gap of 1.53 eV with a lower highest occupied molecular orbital (HOMO) value of 5.50 eV. A bottom‐contact bottom‐gate organic thin‐film transistor device fabricated using DPFN‐DPPF thin film exhibits a hole mobility of 0.20 cm2 V−1 s−1 in air. 其他題名： Macromol. Chem.
