Alkoxy-Substituted Quadrupolar Fluorescent Dyes [PDF]
Journal of the American Chemical Society, 2022 Polar and polarizable π-conjugated organic molecules containing push-pull chromophores have been investigated extensively in the past. Identifying unique backbones and building blocks for fluorescent dyes is a timely exercise. Here, we report the synthesis and characterization of a series of fluorescent dyes containing quadrupolar A-D-A constitutions ...

Analytical Chemistry, 2002
Two derivatives of fluorescein, termed "xanthamides," were prepared from fluorescein, an inexpensive dye. Relative to fluorescein, which contains a 6-phenolic OH and a 2'-carboxyl, the first derivative (5) contains a carboxymethyl ether at the 6-position and a secondary amide of dimethylamine at the 2'-position.

Alcian yellow as a fluorescent dye
Acta Histochemica, 1989Fluorescence characteristics of the cationic dye Alcian yellow are described. Under ultraviolet excitation, the chromatin and basophilic cytoplasm from cell smears show a blue-white emission, which depends on the presence of nucleic acids. Glycosaminoglycans-containing structures (mast cell granules, cartilage matrix) appear brightly fluorescent.

Investigation of the Fluorescence Spectra of the Fluorescent Dyes
Advanced Materials Research, 2014The experiment was conducted to study the effects of concentration, temperature and solvent on the luminescence decay curves obtained in laser-induced fluorescence (LIF) experiment from fluorescent orange dye. Sample solutions of fluorescence dye were prepared by mixing with ethanol solvents at different concentration. The sample was illuminated with a

Terrylenimides: New NIR Fluorescent Dyes
Chemistry – A European Journal, 1997AbstractTerrylenimides 3 and 4 represent a new class of blue colorants, exhibiting absorption maxima at 650 to 700 nm and fluorescence emissions in the NIR region (673 to 750 nm). The terrylenimides were synthesized by means of various organometallic coupling reactions, catalyzed by transition metal complexes (Nio, Pdo) and starting from the aromatic ...

The metachromasia of fluorescence of acridine dyes
Histochemie, 19621. Fluorescence- and absorption spectra of a number of acridine dyes were measured at several concentrations, in different solvents and at various pH and temperatures. 2. In aqueous solutions metachromatic shifts are visible with all dyes — except acridine-yellow — with increasing concentrations, even when the dye is present as di- or trivalent ions in
