摘要：
The solvatochromic behavior of novel carbazole containing dyes obtained by the condensation of 9-ethyl-9H-carbazole-3-carboxaldehyde and 9-ethyl-9H-carbazole-3 6-dicarboxaldehyde with (1-phenyl-ethylidene) propanedinitrile and ethyl-2-cyano-3-phenyl-2-butenoate are described The dyes were characterized by FT-IR H-1 NMR C-13 NMR Elemental analysis and Mass spectra DSC -TGA analysis showed these dyes are thermally stable up to 300 degrees C The UV-Vis absorption and fluorescence emission spectra of the dyes were studied in solvents of differing polarity the dyes exhibited positive solvatochromism and solvatofluorism (C) 2010 Elsevier Ltd All rights reserved
