【Abstract】 A new Schiff base with π-conjugated system has been synthesized. The structure was characterized by 1H NMR,13 C NMR ESI-MS,IR,and elemental analysis. Quantum chemical calculations based on time-dependent density functional theory( TDDFT) were performed to investigate the absorption spectrum. The absorption spectra and one-photon fluorescence were experimentally studied. The results indicate that the compound possess excellent spectral properties. Therefore,it may have potential applications in optic-electronic materials.更多还原
