Koraiem, Ai published the artcileNovel cyanine dyes based on N-bridgehead heterobicyclic: synthesis, solvatochromism and physicochemical studies, HPLC of Formula: 606-55-3, the publication is Organic Chemistry: An Indian Journal (2018), 14(2), 125, database is CAplus.
Cyanine dyes of zero methine, monomethine, acyclic metro cyanine dyes incorporating pyrazolo (3,2-a) pyridine, payroll (3,4-c) pyrazolo (3,2-a) pyridine or quinolin (1,2-a) imidazo (2.3-c) pyrano (2,3-c) pyrazole and imidazo (1,2-a) quinoline resp. were synthesized and characterized by UV-Visible, elemental and spectral anal. The absorption spectra properties of such selected dyes were investigated in 95% ethanol to attempt and throw some light on the influence of such new heterocyclic nuclei and to compare or evaluate spectral behaviors. The solvatochromic behavior and color changes of some selected newly synthesized cyanine dyes are observed in solvents having different polarities. This permits a selection of optimal solvent (fractional solvent) when such dyes are applied as photosensitizers. The spectral behavior of some selected cyanine dyes in mixed solvents of different polarities has been studied to estimate number of hydrogen bond formed between the solute & solvent mols. and to allow measurement of certain energies such as hydrogen bonding, orientation and free energies.
