中文摘要: 采用Stille交叉偶联反应，合成了基于6-烷基吡咯[3，4-d]哒嗪-5，7-二酮（PPD）与吡咯并吡咯二酮（DPP）结构单元的受体-π-受体（A₁-π-A₂）型共轭聚合物（PPPD-DPP）。采用热重分析仪、紫外分光光度计、电化学工作站等表征了聚合物PPPD-DPP的性能，系统地研究了聚合物的热性能、光物理性能、电化学性能及晶体管性能。结果表明：聚合物PPPD-DPP具有良好的热稳定性，热分解温度达到376℃；薄膜的最大吸收峰位于702 nm，光学能带隙为1.27 eV；有较低的最高占据分子轨道能级（HOMO，-5.23 eV）。基于PPPD-DPP的有机薄膜晶体管（OTFTs）器件在真空中显示出双极性传输特性，最高电子和空穴迁移率分别为0.030 cm²/（V·s）和0.054 cm²/（V·s），在空气中PPPD-DPP器件则表现出明显的p型传输特性，空穴迁移率提升至0.121 cm²/（V·s）。

Abstract:An acceptor-π-acceptor(A₁-π-A₂) conjugated polymer(PPPD-DPP) based on 6-alkylpyrroles[3,4-d]pyridazine-5,7-dione(PPD) and diketopyrrolopyrrole(DPP) units was synthesized by Stille cross-coupling reaction.The thermal,optical, electrochemical and transistor properties of the polymer were studied by thermogravimetric analyzer,UV-Vis-NIR absorption spectrophotometer and cyclic voltammetry.The polymer PPPD-DPP showed excellent thermally stable with a decomposition temperature of 376℃ and broad absorption in the near infrared region.PPPD-DPP also had low band gap of 1.27 eV and deep highest molecular orbital energy level(HOMO) of -5.23 eV.Polymer-based organic thin film transistors(OTFTs) devices exhibited ambipolar charge transport under vacuum and yielded the mobilities of 0.030,0.054 cm²/(V·s) for electron and hole,respectively.The devices were also investigated in air and diaplayed p-type transport behavior with a hole mobility of 0.121 cm²/(V·s).
