Photophysical Properties of Carbazole Derivative DPSPC Doped Composite Glass
A D-π-D type of organic dye 2,7-di[4-(N,N-diphenylamino)styryl]-9-n-pentyl-9H- carbazole (DPSPC) with diphenylamine as donor group and styrene-carbazole-styrene as conjugation bridge has been synthesized. The photophysical properties of the dye in different solvents and poly methyl methacrylate/organic modified sol-gel glasses are researched. The results indicate that the fluorescence properties of the organic dye in composite glass increase relative to that in solvents and there are no fluorescence quenching in high doped concentration in composite glass matrixes. The dye has higher stability in the composite glass than that in solution.
