The invention discloses a star-shaped triphenylamine derivative, and a preparation method and applications thereof. According to the preparation method, 3,4-ethoxylene dioxy thiophene is reacted with n-butyllithium and tributyl tin chloride successively so as to obtain an intermediate 1; under the catalytic action of palladium, the intermediate 1 is reacted with tris(4-bromophenyl)amine so as to obtain an intermediate 2; under the action of phosphorus oxychloride, the intermediate 2 is reacted with N,N-dimethylformamide so as to obtain an intermediate 3; and at last, the intermediate 3 is reacted with malononitrile in the presence of triethylamine so as to obtain a finished product N,N,N-tri[4-(5-dicyanovinyl-3,4-ethenyldioxy-2-thienyl) phenyl]amine. The star-shaped triphenylamine derivative is possible to be used as a high efficiency organic photovoltaic cell electron donor material because of the unique molecular structure and large conjugated system. 本发明公开了种星型三苯胺衍生物及其制备方法与应用。该制备方法是先将3,4-乙烯二氧噻吩先后与正丁基锂和三丁基氯化
