Synthesis Of Novel Compounds Containing A Thiophenylacrylonitrile Moiety And Their Light Emitting Property

This dissertation includes five chapters.Chapter one is mainly the development of Hartwig-Buchwald coupling reaction catalyzed by palladium;Chapter two is mainly the progress in Suzuki coupling reaction;Chapter three is the synthesis and photophysical properties of novel thiophenylacrylonitrile derivatives containing a triphenylamine moiety;Chapter four is the synthesis and photophysical properties of novel biphenyl containing a thiophenylacrylonitrile moiety;Chapter five is the synthesis of several organosilicon materials with amino group.In chapter one,we reviewed the progress of palladium-catalyzed Hartwig-Buchwald coupling reaction mainly from the reaction conditions and ligand.In chapter two,we made a review of the development of palladium-catalyzed Suzuki coupling reaction.In chapter three,we used the Pd(OAc)₂/P(o-tolyl)₃ system to promote the synthesis of novel thiophenylacrylonitrile 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 in CH₂Cl₂ were investigated.In chapter four,we used the Pd(PPh₃)₄ to promote the synthesis of novel biphenyl containing a thiophenylacrylonitrile 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.The fifth chapter detailed work related to the synthesis of several organosilicon materials with amino group.
