| 中文摘要: |
| 合成了两个侧链含有2，2，6，6-四甲基哌啶-1-氧自由基单元（TEMPO）的1，4-吡咯并吡咯二酮（DPP）共轭聚合物PDPP4T-1和PDPP4T-2，并开展了其半导体性质研究。薄膜场效应晶体管器件测试结果显示，相对于不含TEMPO的聚合物PDPP4T，PDPP4T-1和PDPP4T-2的场效应器件性能有所降低，不过，含TEMPO的聚合物器件性能最高仍达到了2.12cm2·V-1·s-1。进一步通过原子力显微镜和X射线衍射对TEMPO引入后导致性能降低的可能原因进行了研究。 |
| 英文摘要: |
| In this paper, the syntheses of two 1,4-diketopyrrolopyrrole (DPP) based conjugated polymers, PDPP4T-1 and PDPP4T-2, in which the molar ratios of the 2,2,6,6-tetramethyl-1-piperidinyloxyl (TEMPO) unit-contianing alkyl chains vs. branching alkyl chains are 1:5 and 1:10 and their semiconductor properties were reported. The test results indicated that introduction of TEMPO units in the alkyl side chains has almost no effect on their electronic configuration of polymer conjugated backbones. The thin films of PDPP4T-1 and PDPP4T-2 exhibit p-type semiconducting properties with hole mobilities up to 2.12 cm2·V-1·s-1, though lower than that of PDPP4T without TEMPO units in the alkyl side chains. Furthermore, their thin films were characterized with AFM and GIXRD to explore the possibilities for their performance variation. |
