Variations in molecular electronic structures related to conformational change are exceedingly attractive because of their key role in the understanding and development of functional processes in molecular electronics and biology. We observed, for the first time, the novel phase switching of a photoactive isomeric molecule, N-(2-mercaptoethyl)-4-phenylazobenzamide (Azo molecule) at a single-mol...

in 0.1 M ionic strength aqueous solution at 120 for the following: 2,4-dihydroxy4'-nitroazobenzene (I), 2,4-dihydroxy-4'-sulfonateazobenzene (II), and p-(2hydroxy-l-naphthylazo) benzenesulfonic acid (III). The reported values of k231 were 4O X 105, 3.6 X 105, and 3.6 X 106 M-1 sec-1. They attributed the much lower values of k23, for these acids than the value3 k23, 2 X 109 M-1 sec-1 kn,' for th...

Textile industries discharge a large quantity of colored wastewater which is harmful to the ecosystem. In this study, two kinds of dyes were investigated: the mono azo Acid Orange 7 (AO7) and diazo Reactive Green 19 (RG19). The photocatalytic degradation of single (AO7, RG19) azo dye and binary (AO7 and RG19 mixture) azo dye aqueous solutions was photocatalyzed by commercial titanium dioxide (T...

There are two independent zwitterion mol-ecules (A and B) in the asymmetric unit of the title compound, C17H11N3O, which belongs to the family of azo dyes. The dihedral angle between the benzene ring and the naphthalene ring system is 6.99 (6)° in mol-ecule A and 4.38 (6)° in mol-ecule B. The azo group adopts an E conformation with respect to the -N=N- bond and each of the independent mol-ecule...

complexes (where tpy = 2,2′:6′,2′′-terpyridine, L = bidentate ligand, n = 0 or 1), because they are used as precursors of aquo complexes, which can finally be converted to oxo compounds. Oxo-ruthenium complexes are useful as catalysts in different reactions, particularly in the catalytic oxidation of water to dioxygen.1,2 As a part of serial studies on the properties of oxoruthenium complexes, ...

The combination of ditopic ligand 4-(8-hydroxyquinoline-5-azo)-benzensulfonic acid (H2QBS) with metal ions (M = Na(+), Pb(2+), Zn(2+), Mn(2+), Cd(2+)) leads to five different coordination polymers (CPs): [Na2(QBS)(H2O)2]n (1 , 3D framework), {[Pb(QBS)(DMSO)]·2((i)PrOH)}n (2·2(i)PrOH, 2D layer), {[Zn(QBS)(DMSO)]·2DMSO}n (3·2DMSO, 1D chain), [Mn(QBS)((i)PrOH)(DMSO)]n (4, 1D ladder), and [Cd2(QBS)...

In this paper, we proposed the effects of Mo thickness on the properties of AZO/Mo/AZO multilayer thin films for opto-electronics applications. The structural, optical and electrical properties of AZO/Mo/AZO thin films were investigated. Optimization of the thin films coatings resulted with low resistivity of 9.98 × 10 Ω-cm, mobility of 12.75 cm/V-s, carrier concentration of 1.05 × 10 cm, maxim...

Numerous heterocyclic azo dyes have been reported for the spectrophotometric determination of Cu(II). Here, we report a new heterocyclic azo dye 1-(2'Chloro-4'-sulphophenyl-3-methyl-4-azo-(2"carboxy-5"-sulphonic acid)-5-pyrazolone [CSMACSP] for the spectrophotometric determination of Cu(II). The method is simple, rapid and sensitive. Light green colour 1:1 (M:L) complex formed between Cu(II) an...
