【Abstract】 N-Ethyl-3-[2-(8-hydroxyquinolin-2-yl)vinyl]carbazole has been synthesized and identified by UV-Vis, 1H NMR, FTIR, MS spectra and elemental analyses. Its photoluminescence properties were meas- ured on an F-250 spectrometer. The geometry structure was optimized and vibration spectrum was predicted by the density functional theory calculations with the B3LYP functional on the level of 6-31G(d,p) basis set. The vibration spectrum predicted was compared with the observed value to be in good agreement.更多还原
