Five novel fluorescent azo disperse dyes were synthesized using different diazotized
aromatic amines followed by coupling with 3-(1, 3-benzothiazol-2-yl) naphthalen-2-ol. These …

Photoswitchable molecules display two or more isomeric forms that may be accessed using
light. Separating the electronic absorption bands of these isomers is key to selectively …

In many areas of the observational and experimental sciences data is scarce. Data
observation in high-energy astrophysics is disrupted by celestial occlusions and limited …

In this work, we have reported four azo dyes having a heterocyclic framework derived from 2-
amino-5-nitrothiazole by a traditional diazo-coupling method in an acidic medium using four …

The space of synthesizable molecules is greater than $10^{60} $, meaning only a
vanishingly small fraction of these molecules have ever been realized in the lab. In order to …

New four acid azo dyes were synthesized from aromatic amines containing acidic group and
3-(1, 3-benzothiazol-2-yl) naphthalen-2-ol by diazotization and coupling reaction. These …

A series of heterocyclic disperse azo dyes having pyridone architecture was prepared by a
simple, economical and highly efficient diazo‐coupling method. In this method, butyl …

A family of stilbenyl-azopyrroles compounds 2a–d and 3a–d was efficiently obtained via a
Mizoroki–Heck C–C-type coupling reaction between 2-(4′-iodophenyl-azo)-N-methyl …

The possibility to characterize the electronic excited state of a spectrally active molecule
based only on the solvatochromic study of electronic absorption spectra is demonstrated …

The structural and optical characteristics of azo dye 4-[(Z)-(6-Nitro-1, 3-benzothiazol-2-yl)
diazinyl] naphthalen-1-ol were examined using UV-visible, FT-IR, and FT-Raman …
