In the paper five new discoumarin-3-carboxamide derivatives were synthesized. All compounds were characterized by IR, NMR, MS and elemental analysis. N,N-(1,3-Phenylene)bis(7-(diethylamino)- coumarin-3-carboxamide) (4) was inves-tigated with X-ray crystallography. Compound 4 belongs to triclinic system with space group P-1, the crystal parameters of 4 were a＝0.8269(14) nm, b＝1.4301(3) nm, c＝2.5533(4) nm, α＝82.55(4)°, β＝86.09(5)°, γ＝79.05(1)°, V＝2.9367(3) nm3, Dc＝1.345 g•cm－3, Z＝2, F(000)＝1256, μ＝0.093 mm－1. The final R1＝0.0622, wR2＝0.1410. Their ultraviolet and fluorescence properties were studied. The results showed that all compounds possess two UV-Vis absorption bands, the absorption maxima were in the visible region from 418 to 441 nm, and the emission maxima were at 450～460 nm. Compounds exhibited high fluorescence quantium yields (0.56～0.65).
