Synthesis of Some New Azo Disperse Dyes and Investigation of Their Solvatochromic Effect
The synthesis and properties of new monoazo dyes derived from the diazonium salts of paminobenzoic acid, 3-trifluoromethyl aniline , 4-trifluoromethyl aniline are considered .Theprepared compounds were characterized by UV-Visible , FT-IR and H NMR spectroscopictechniques . The effect of varying solvent upon the absorption ability of p-amino benzoic acidcoupled with 4,4 —diethyl aniline , anilin...

متن کاملGreen Perylene Bisimide Dyes: Synthesis, Photophysical and Electrochemical Properties
Three asymmetric amino-substituted perylene bisimide dyes with different n-alkyl chain lengths (n = 6, 12, or 18), 1-(N,N-dialkylamino)perylene bisimides (1a-1c), were synthesized under mild condition in high yields and were characterized by ¹H NMR, ¹³C NMR (nuclear magnetic resonance), HRMS (High Resolution Mass Spectrometer), UV-Vis and fluorescence spectra, as well as cyclic voltammetry (CV)...
متن کاملSynthesis Of Some Novel Azo Dyes And Their Dyeing, Redox And Antifungal Properties
Azo dyes are widely used colorants in consumer products such as leather, textiles, agriculture, cosmetics and in laboratories as indicators. This paper describes the synthesis of some novel azo dyes starting from 3-nitro salicylic acid. The synthesized dyes were investigated for their redox potentials, evaluated for their dying ability on cotton fabrics, resistivity against the fungi growth on ...
متن کاملSynthesis, characterization and ion-exchanging properties of novel oligomeric azo dyes
Diazotization of p-toluidine and coupling with 3-amino-phenol-Formaldehyde (APF) resin give oligomaric azo dye TAPF, based on 3-amino-phenol-Formaldehyde (APF) polymer. The TAPF was then treated with 5-chloro methyl-8quinolinol hydrochloride in the presence of a THF in alkaline medium (pH 9-10) at room temperature for 7 hrs. The resultant oligomaric ligand designated as azo polyphenol-formaldeh...
