Shindy, Hassan Abazied published the artcileEffects of chemical structure, solvent and solution pH on the visible spectra of some new methine cyanine dyes, Quality Control of 606-55-3, the publication is European Journal of Chemistry (2014), 5(3), 451-456, 6 pp., database is CAplus.
Some new dimethine and bis-dimethine, 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 synthesized. Effect of chem. structure on the electronic visible absorption spectra of all the synthesized cyanine dyes was investigated in 95% ethanol solution Effects of solvent and/or solution pH on the electronic visible absorption spectra of some selected synthesized cyanine dyes were also examined in pure solvents having different polarities and/or in aqueous universal buffer solutions, resp. Structural confirmations were carried out through elemental anal., mass spectroscopy, IR and 1H NMR spectra.
