Abstract:

A new D-π-A type of single-branched organic dye 1(1-(2-naphthyl)-3-(N-ethyl- carbazolyl)-prop-2-en-one) and a new A-π-D-π-A V type of two-branched organic dye 2(3,6-bis［1-(2-naphthyl)-prop-2-en-one］-N-butyl-carbazole) are synthesized.The photophysical properties of the dyes in different solvents and polymer matrices are investigated.The results reveal that two-branched organic dye 2 has stronger absorption and fluorescence emission than dye 1.With little aggregation of molecules，the fluorescence intensity of the two organic dyes in the polymer matrices is greatly increased compared with that in the solvents at the same concentration.
