Picosecond Switchable Azo Dyes
Chemistry – A European Journal, 2019AbstractAzo dyes that combine electron‐withdrawing thiazole/benzothiazole heterocycles and electron‐donating amino groups within the very same covalent skeleton exhibit relaxation times for their thermal isomerization kinetics within milli‐ and microsecond timescales at room temperature.

Dyes and Pigments, 2016
Abstract Any liquid azo dyes, in which auxochrome such as dialkylamino, alkoxy, and amino group is attached in a molecule, were produced. In a series of 2-alkyl-4’-(dimethylamino)azobenzenes, the butyl, hexyl, octyl, and dodecyl derivatives were liquid at room temperature, whereas the propyl, 1-methylethyl, 1-methylpropyl, 1,1-dimethylethyl, and ...

Recent Applications of Azo Dyes: A Paradigm Shift from Medicinal Chemistry to Biomedical Sciences.
Mini-Reviews in Medical Chemistry, 2020Azo molecules are one of the fascinating organic molecular architectures with azo bond (-N=N-). Since the last century, the bright colored azo molecules are used as dyes for printing, food, paper, cosmetic laser, electronics, optics, material sciences ...

Acta Polymerica, 1987
AbstractA series of new polymerizable azo dyes containing the methacryloyloxy group were prepared. Their melting points, yield, colour, solubility and absorption in the UV‐visible range were characterized, and the relationship between their properties and structure was evaluated. The characteristics of radical homopolymerization of one of the azo dyes,

Heterocyclic azo dyes. IV. Azo Dyes Containing the Quinoline Nucleus
Journal für Praktische Chemie, 1973AbstractThe synthesis, some dyeing and fastness properties of several new monoazo dyes derived from 6‐amino‐ and 6‐hydroxy‐quinolines when applied as dispersed dyes on nylon 6 are described. Preliminary correlations between light fastness and chemical structure are attempted.

A Sensor Array for the Nanomolar Detection of Azo Dyes in Water.
ACS Sensors, 2020Azo dyes are ubiquitous pollutants that contaminate water supplies and threaten human, biota, and ecosystem health. Their detection and discrimination are a considerable challenge owing to the numerous structural, chemical, and optical similarities ...

Carcinogenic azo dyes, dye-binding and liver glutathione
Biochemical Pharmacology, 1964Abstract Good correlations have been found between the relative carcinogenic activities of azo dyes and the ability of these compounds to increase the liver glutathione (GSH) content and to form bound dye (B.D.) in the livers of male rats 24 hr after intraperitoneal (i.p.) injection of equimolar amounts of the dyes.

Spectroscopic ellipsometry investigation of azo dye and azo dye doped polymer
The European Physical Journal Applied Physics, 2006The optical constants of azo dye (Methyl Red (MR)) and azo dye doped polymer (ADP) (Polymethylmethacrylate (PMMA)) MR/PMMA have been investigated using Variable Angle Spectroscopic Ellipsometry (VASE). Pure MR was modeled using Lorentz formula with three oscillators. A Bruggmann effective medium approximation layer was employed with three constituents (

Multiple azo disperse dye sensitization mainly due to group sensitizations to azo dyes
Contact Dermatitis, 1996A female patient, with a previous episode of contact dermatitis caused by a blue dress developed similar dermatitis due to a navy ‐blue dress. Patch tests revealed multiple allergic positive reactions to paraphenylenediamine (PPD). The navy‐blue dress, its extracts, 6 azo disperse dyes in a textile series, as well as 3 dye components, including ...
