摘　　要：测定了1,4-双(取代苯乙炔基)苯(Ⅰ)和反,反-1,4-双(β-取代苯乙烯基)苯(Ⅱ)的紫外光谱、荧光光谱.用CNDO/S-CI和HMO方法对苯乙炔、二苯乙炔和(Ⅰ)及苯乙烯、1,2-二苯乙烯和(Ⅱ)的激发能进行了计算和研究.讨论了化合物结构对光谱的影响.The Ultra-Violet absorption spectra and the fluoresence emission spectra of 1,4-bis (substituted phenylethynyl) benzene ( Ⅰ ) and trans, trans 1, 4-bis (substituted phenylethenyl) benzene ( Ⅰ ) were determined. The excited energies of phenylacetylene, diphenylacetylene, Ⅱ, styrene, stilbene, and Ⅱ were computed using CNDO/S-CI and HMO methods. The influences of the structures of the compounds on spectra were discussed.
