摘要：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 morphology of thin films depends on the substrate temperature. The film OFET devices based on SiPy were constructed and exhibited p-type performances.
