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 ...
Specific and non-specific interaction effect on the solvatochromism of some symmetric (2-hydroxybenzilydeamino)phenoxy Schiff base derivatives
(Elsevier Science BV, 2016)
