Abstract A new azo compound 2‐(2‐hydroxyphenylazo)‐indole‐3/‐acetic acid was
synthesized. It is a yellow solid when freshly prepared but upon exposure to light turns red …

In this manuscript, two series of azo dyes preparing by coupling diphenylamine and N-
methyl diphenylamine and diazotized substituted anilines bearing various substituents were …

In this study, azo dyes containing an imine group were synthesised by coupling p-
hydroxybenzylidene aniline with the diazonium salts of p-toluidine, 4-aminophenol, aniline …

Six mono azo disperse dyes were synthesized using diazotized dimethyl-4-amino-5-
nitrophthalate (5) and dimethyl-3-amino-4-nitrophthalate (5') followed by the diazo coupling …

A new two series of phenylazo indole dyes was synthesized and the structures of the dyes
were confirmed by UV–vis, FT-IR, HRMS and 1 H/13 C NMR spectroscopic techniques. Five …

Acridine group of dyes are well known in the field of development of probes for nucleic acid
structure and conformational determination because of their relevance in the development of …

In this paper three different “push-pull” 4-aminoazobenzene dyes have been synthesized in
order to characterize their photochromic behavior in different solvents. The molecular …

A monoazo disperse dye (DMA) has been prepared by diazotizing 4-aminoacetophenone
and coupling with N, N-dimetylaniline. It was fully characterized using IR, 1H-NMR, 13C …

In search of achieving some specific fluorescent and biological applications, azo-based
compounds 1 and 2 with robust H-bonding and strong peptide properties were synthesized …

A new monomeric tricationic cyanine dye TO-3c-7Cl–analog of Thiazole Orange (TO), has
been synthesized using an environmentally benign and simple method and its …
