| This dissertation includes four chapters. Chapter one reviewed the development of the organic light-emitting materials; Chapter two is mainly the progress in palladium-catalyzed C-N coupling reaction and C-C coupling reaction; Chapter three is the synthesis and photophysical properties of novel biphenyl derivatives containing a furanacrylonitrile moiety; Chapter four is the synthesis and photophysical properties of novel acrylonitrile derivatives containing a triphenylamine moiety.In chapter one, we made a summary of the discovery of organic electroluminescence. Then, we summed up their applications in the development of display technology. At last, we summarized the organic light-emmiting materials on the triarylamines from several important journals.In chapter two, we reviewed the progress of palladium-catalyzed Hartwig-Buchwald coupling reaction and Suzuki coupling reaction mainly from the reaction conditions and ligands.In chapter three, we reported the synthesis and photophysical properties of a series of novel furanacrylonitrile derivatives containing biphenyl groups.In chapter four, we used the Buchwald-Hartwig cross coupling reaction and Suzuki coupling reaction to promote the synthesis of novel acrylonitrile derivatives containing a triphenylamine moiety, and we also studied their light emitting properties. Structures of products were characterized by FT-IR,1H NMR,13C NMR, MS and elemental analyses. The UV-vis absorption and photoluminescent (PL) spectra of the compounds were investigated. |
