(Hacettepe University, 2012)
E-1-((2-hydroxy-5-methylphenyl)diazenyl)naphthalene-2,7-diol’ün ve akrilat türevlerinin ve onların krom komplekslerinin farklı çözücüler, pH ve sıcaklıklardaki UV-VIS davranışları tespit edildi. Çözücü içinde boyalar azo ...
Synthesis, characterisation and DFT calculations of azo-imine dyes
(Turkish Chemical Society, 2018)
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, p-chloroaniline, p-fluoroaniline and p-nitroaniline. ...
Spectroscopic and thermal properties of newly mixed azocalix[4]arene ester derivatives
(Elsevier B.V., 2014)
The mono-, di-, tri-, and tetra-acryloyl esters of p-chloroazocalix[4]arene which include the first examples of mixed azo ester dyes were synthesized by reacting acryloyl chloride with sodium salts of p-chloroazocalix[4]arene ...
Structural, absorption, and molecular properties of o,o'-dihydroxyazo resorcinol dyes bearing an acryloyloxy group
(Elsevier B.V., 2017)
To the best of our knowledge, this is the first study reporting the synthesis and characterization of o,o?-dihydroxyazo dyes bearing an acryloyl group. The o,o?-dihydroxyazo dyes were synthesized through coupling of ...
