摘要:
利用Sonogashira偶联反应在芘的1,3,6,8位引入炔键合成了一个X型化合物(SiPy).它的光物理性质、热学性质、薄膜形态和有机场效应晶体管性质被研究.热重分析结果表明SiPy具有高的稳定 性.原子力显微镜图像显示SiPy的薄膜形态依赖于衬底的温度.基于SiPy的薄膜OFET器件被制作,SiPy呈现p型半导体特征.

Pyrene Derivate Functionalized with Acetylene for Organic Field Effect Transistors
Zuo-qin Liang*,Jie Zhou,Xiao-mei Wang,Xu-tang Tao
Abstract:
A new X-shaped compound (SiPy) functionalized with acetylene bonds in the 1-, 3-, 6-, and 8-positions of the pyrene core has been synthesized by Sonogashira coupling reactions. Its photophysical, thermal, and organic field effect transistor (OFET) properties as well as the film morphologies have been investigated. SiPy exhibits high stability which is evidenced by thermal gravimetric analysis. The atomic force microscopy images reveal that the morphol-ogy of thin films depends on the substrate temperature. The film OFET devices based on SiPy were constructed and exhibited p-type performances.
