Studies on the Structure and Fluorescence Spectra of 2-(4'-i-pr-Styryl)-5-Phenyl-Benzoxazole

Abstract

Abstract: 2-(4'-i-pr-styryl)-5-phenyl-benzoxazole was synthesized by condensation of the 5-phenyl-methyl benzoxazole with p-i-pr-benzaldehyde in the medium of KOH/DMF.This compound was identified by elemental analysis, IR, NMR, UVabsorption, FLemission spectra and X-ray diffraction. The molecular structure was confirmed that it belongs to triclinic system. The results of CNDO/s calculation showed that the fluorescence emission spectra of compound (Ⅰ), compared with its model compound (Ⅱ), was red shifted. The FLintensity of compound (Ⅰ) is three times greater than that of compound (Ⅱ). This is consistent with the experimental result.

Key words: Benzoxazole, Fluorescence emission spectrum, X-ray diffraction analysis
