In furtherance of our research on the design, synthesis and study of electrogenerated chemiluminescence (ECL) of new donor substituted phenylquinolinylethynes, we report here more new series with the aim of studying the effect of positional isomerism on their overall photophysical properties with a special focus on ECL. For this study we have chosen 2-, 3-, and 4-(p-substituted phenyl)ethynylqu...

The electrochemistry and electrogenerated chemiluminescence (ECL) of three phenanthrene derivatives, 3,6-diphenyl-9,10-bis-(4-tert-butylphenyl)phenanthrene (TphP, T1), 3,6-di(naphthalen-2-yl)-9,10-bis(4-tert-butylphenyl)phenanthrene (TnaP, T2), and 3,6-di(pyrene-1-yl)-9,10-bis(4-tert-butylphenyl)phenanthrene (TpyP, T3), are investigated in an acetonitrile:benzene (v:v = 1:1) solvent. Cyclic vol...

We fabricated electrogenerated chemiluminescence (ECL) cells having titanium dioxide nanoparticles (TiO2 NPs) as an electron injection layer (EIL). The EIL paste, which was spin-coated on a cathode substrate, annealed at three different temperatures of 250°C, 350°C, and 450°C. A tris(2,2'-bipyridine)ruthenium(II) solution used emitter. ECL performances were significantly increased with the incr...

In tetrahydrofuran, the electrochemical reduction of Cp2TiIVCl2 (2 mM) generated three titanium(III) complexes which were in equilibrium: [Cp2TiCl2]•−, [Cp2TiCl]• and (Cp2TiCl)2. Although anion radical [Cp2TiCl2]•− was main species produced under these conditions, cyclic voltammetry investigations clearly showed that proportion electrogenerated TiIII can be modified as a function amounts chlori...

Reactivity of (2E)-3-(3,4-dihydroxyphenyl)prop-2-enoic acid (caffeic acid), classified as a hydroxycinnamic (HCA) derivative, toward electrogenerated superoxide radical anion (O2•−) was investigated through cyclic voltammetry, in situ electrolytic electron spin resonance spectrometry, and ultraviolet–visible spectrometry N,N-dimethylformamide (DMF), aided by density functional theory (DFT) calc...
