Azo dyes, compounds having double bond linkage between two nitrogen atoms, are widely
found as a main scaffold in a massive library of organic species that exhibit promising …

This review gathers the hyperpolarizabilities of monomeric azo dyes studied by various
analytical techniques-electric-field-induced second-harmonic generation (EFISHG), hyper …

Azo molecules, characterized by the presence of aN= N-double bond, are widely used in
various fields due to their sensitivity to external stimuli, ch as light. The emergence of …

In this review, we present a systematic and comprehensive summary of the recent
developments in the synthetic strategies of 2-(2-hydroxyarylsubstituted)-benzothiazole …

There are a wide variety of textile dyes including reactive, direct, vat, sulfur, disperse, basic,
and acid dyes. Therefore, the classification of dyes has become mandatory due to the …

A number of azo pyrazole derivatives and novel Schiff bases derived from azo diamino
pyrazole were synthesized. These included 4-(2-arylhydrazono)-4H-pyrazole-3, 5-diamines …

Nowadays, organic chemists are interested in the field of heterocyclic chemistry due to its
use in the synthesis of a great variety of biologically active compounds. Heterocyclic …

In this study, four novel coumarin-thiazole-based azo dyes were prepared by coupling N-
methyl-N-phenylaniline and 3-methyl-1-phenyl-2-pyrazoline-5-one with coumarin-2 …

The design, synthesis, and use of four new thiophene-based dispersed azo dyes with
salicylic and carboxylic acid acceptors are shown in this work. The produced dyes exhibit a …

A novel series of new 2-arylazo-thiazole dyes pendant to fluorene moiety was synthesized.
The novel azodyes have been accessed via the reaction of hydrazonoyl halides with the 2 …
