Abstract: 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-CIand HMOmethods.The influences of the structures of the compounds on spectra were discussed.

Key words: 1,4-Bis (substituted phenylethynyl) benzene, Trans, trans 1,4-bis (β-substituted phenylethenyl)benzene, UV spectra, Fluorescence spectra, CNDO/S-CI and HMO methods
