本文介绍了一种含有1,4-二酮吡咯并吡咯和铂的金属有机共轭聚合物。通过紫外-可见吸收光谱及电化学测得该聚合物的LUMO和HOMO分别为-3.4e V和-5.3e V。通过旋涂方法制备了该材料的底栅底接触场效应器件,并在退火至160℃之后测得其最高性能为:空穴迁移率1.0×10-3cm2·V-1·s-1,开关比105,阈值电压-15V。同时,通过原子力显微镜和X射线衍射对材料薄膜的退火过程进行了研究。
This article describes a metal-organic conjugated polymer containing 1,4-diketopyrrolopyrrole and platinum. The LUMO and HOMO of the polymer were -3.4 eV and -5.3 eV, respectively, as determined by UV-Vis absorption and electrochemistry. The bottom-gate bottom contact field effect device of the material was prepared by spin-coating method and its maximum performance was measured after annealing to 160 ℃: the hole mobility of 1.0 × 10-3cm2 · V-1 · s-1, the switch Than 105, threshold voltage -15V. At the same time, the annealing process of the material thin films was studied by atomic force microscopy and X-ray diffraction.
