| Résumé : |
New polymethine cyanine dyes, including tetramethine and bis-tetramethine cyanine dyes derived from benzo[2,3-b;2',3'-b']bis-pyrazolo[4,5-b]-1,4-(oxa-, thia- and pyra-)-zine-6,12-dione, were synthesised. Absorption spectra for all the synthesised cyanine dyes were examined in 95% ethanol. The solvatochromism and halochromism for some selected dyes were investigated in pure solvents and in aqueous universal buffer solutions, respectively. Structural confirmations were carried out through elemental and spectroscopic analysis. |
