New 2-D π-Conjugated Materials:Designs、synthesis And Properites

π-extension systems with two-dimensional(2-D) conjugation for FET devices have not been extensively developed. Although the performances of 2-D PAHs were not as remarkable as 1-D those of acenes, it is worthy to pay much attention on them. Because 2-D PAHs can be constructed through the straightforward strategy of chemical oxidants induced dehydrogenation steps(namely, Scholl reaction). The Scholl reaction has been extensively utilized for the synthesis of planar PAHs.A series of new 2-D conjugation materials were prepared by Scholl reaction and Cross-coupling reactions such as Suzuki and Sonogashira. In this article, a new type of Scholl reaction system was builded base on 3,3’-bithiophene nuclear, in the system, Scholl reaction mechanism was discussed. Base on this synthetic work, we get an unexpected dimer. We try to do some test to determine the structure and the mechanism of reaction kinetics has been studied. In addition, we try to synthesis bigger two-dimensional conjugate material(tilted rylene) which was base on pyrene and perylene. Most important of all, the new materials may play an important role in organic electronics.
