UV-spectral changes for some azo compounds in the presence of different solvents
(Elsevier Science BV, 2011)
The electronic absorption spectra of four azo dyes with different substituents (such as Cl, I, OH) are determined at room temperature in twenty-one solvents with different polarities. The electronic transitions of azo dyes ...
Electrochemical Determination of Paracetamol by a Novel Derivative of Formazan Modified Pencil Graphite Electrode
(IEEE-Inst Electrical Electronics Engineers Inc, 2014)
A modified electrode, based on electrodeposition of 5,5'-(oxybis(4,1-phenylene))bis(3-(2-hydroxyphenyl)-1-phenylformazan (BF) onto pencil graphite (PG) electrode, was investigated for the determination of paracetamol in ...
Theoretical and Experimental Studies of Some Schiff Base
(2015)
Aldehitlere ait karbonlar aminlerin nükleofilik saldırmasına uygundur. Bu reaksiyonun sonunda üründe C=O çiftli bağı yerine C=N bağı oluşur. Bu tip birleşiklere Schiff bazı denir. Bu çalışmada Schiff bazları 2-kinolin ...
Theoretical Investigation of Certain Tea Compounds in Aqueous and Blood Phases
(Anadolu Üniversitesi, 2012)
In this study, certain theoretical properties of tea compounds, such as acidity constant, stability, reactivity, geometry and energy have been calculated prior to laboratory studies to understand the basic principles ...
A Theoretical Study on Proton-Gain Behaviors of Some Azaindole Derivatives
(Anadolu Üniversitesi, 2011)
The acidities, relative stabilities (RS), nucleophilicities (Ƞ ) and proton affinities (PA) of seven azaindole molecules were determined in both gas and liquid phases using semi-empirical AM1, PM3 and PM5 methods. The ...
Synthesis, characterization, tautomerism and theoretical study of some new Schiff base derivatives
(Pergamon-Elsevier Science LTD, 2011)
New Schiff base derivatives were prepared by the condensation of 5-chloro and 5-bromo salicylaldehyde with bis(o-aminophenol)ethers. Five bis(o-nitrophenol)ether compounds were synthesized using some ditosylate, ...

Synthesis, crystal structure, optical and electrochemical properties of novel diphenylether-based formazan derivatives
(Royal Soc Chemistry, 2015)
In this study, formazans 5a-5h were synthesized by coupling the reactions of substituted phenylhydrazone compounds 3a-3h with diazonium salt of 4-chloro-2-phenoxybenzenamine (4). The substituted phenylhydrazones 3a-3h were ...
Solvatochromism and electronic structure of some symmetric Schiff base derivatives
(Elsevier Science BV, 2015)
In this present work, we have investigated electronic absorption spectra of three symmetric Schiff bases in fourteen spectroscopic grade solvents which have different polarities. The electronic transitions have been evaluated ...
