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 UV spectra and fluorescence spectra of 1,4-bis (substituted phenylethynyl) benzene (Ⅰ) and trans-1,4-bis (β-substituted styryl) benzene The excitation energies of phenylacetylene, tolane, (Ⅰ) and styrene, stilbene and (Ⅱ) were calculated and studied by the methods of -CI and HMO. The influence of the structure of the compounds on the spectra was discussed.
