Abstract:

The UV-Vis absorption spectrum of ZrO2 precursor solution containing 4-(phenylazo)benzoic acid (C6H5N=NC6H4COOH) reversibly changed accompanied with reversible change of the spectrum of 4-(phenylazo)benzoic acid by light irradiation. However, the spectrum of ZrO2 precursor solution containing azobenzene (C6H5N=NC6H5) did not change accompanied with reversible change of azobenzene by light irradiation. Furthermore, the back reaction of ZrO2 precursor solution containing 4-(phenylazo)benzoic acid by visible light irradiation was suppressed even if the back reaction of 4-(phenylazo)benzoic acid h

Abstract:

A new photochromic ZrO2 precursor solution was prepared using zirconium tetra-n-butoxide, 4-(phenylazo)benzoic acid and ethyleneglycol monomethylether. The ZrO2 precursor solution was irradiated with ultraviolet light (UV) at room temperature. After that, UV-irradiated precursor solution was irradiated with visible light (Vis) at room temperature. UV-Vis spectra were measured before irradiation, after UV irradiation and Vis irradiation. Changes of UV-Vis spectra indicated that the new ZrO2 precursor including 4-(phenylazo)benzoic acid shows photochromism. The phenomena have synchronized with r

Abstract:

In this paper, we designed and synthesized a novel phenylazo-based fluorescent probe (RHN) for the sensing and imaging of hypochlorous acid (HClO) in mitochondria in living cells. In this process, HClO promoted the oxidation of the phenylazo group to generate a free Rhodol fluorophore moiety, which in turn restored strong fluorescence and realized the detection of HClO. As expected, RHN exhibited high selectivity, high sensitivity and rapid response, with detection limits as low as 22 nM (1.155 ng/mL). Importantly, the results of the cell imaging experiments indicated that RHN has the ability

Abstract:

The azo-hydrazone tautomerism of 4-phenylazo-1-naphthol has been studied in ethanol-water and acetone-water systems and at high pressures. The hydrazone form is favoured by adding water to organic cosolvents and by applying pressure. The effects of solvent polarity and pressure on the equilibrium constant (KT) between the tautomers were examined by using Kirkwood-type equations applied to chemical equilibrium. Remarkable deviations were observed in the Kirkwood plots for both types of mixtures. Solvent-induced polarization, especially of the hydrazone form in a high polarity region, was sugges

Abstract:

A hybrid surface exhibiting a fast and reversible switch between hydrophobic and hydrophilic states was prepared by spin-coating a porous TiO<sub>2</sub> layer by a mixture of TiO<sub>2</sub> nanoparticles with 11-(4-phenylazo)phenoxy undecanoic acid (denoted as the AzoC11 acid).

Abstract:

3- and 4-substituted 5-phenylazo derivatives of 2,4-thiazolidinedione were prepared as potential biologically active fungicides. The kinetics of coupling of 4-sulfobenzenediazonium salt with 2,4-thiazolidinedione and 3-methyl-2,4-thiazolidinedione have been studied and the results have been compared with kinetic data of coupling reaction of 3-methyl-5-isoxazolone.
