【Abstract】 Three coumarinyl-schiff base compounds were synthesized from coumarin, and characterized by Element Analysis,IR and 1HNMR. The fluorescent spectra of Compound 4 and 5 were determined, it was found that the compounds showed two-photon induced fluorescence, the coumarinyl-schiff base unit had the potential application in forming new effective organic two-photon induced fluorescence (TPIF) molecules.更多还原
