Polymer-Controlled Synthesis of 1-(2-Pyridylazo)-2-Naphthol Hierarchical Architectures
The self-assembly of organic 1-(2-pyridylazo)-2-naphthol (PAN) into hierarchical architectures, such as microfibers, microrods, and sheaflike structures, in solution was successfully achieved by reprecipitation method with the assistance of thermoresponsive diblock copolymer poly(N,N-dimethylacrylamide)-b-poly(N-isopropylacrylamide) (PDMA-b-PNIPAM). It was found that the morphology modification...
متن کاملLiquid chromatography of palladium and non-ferrous metal chelates with 1-(2-pyridylazo)-2-naphthol.
1-(2-Pyridylazo)-2-naphthol has been used for extraction concentration of palladium, copper, cobalt and nickel from aqueous solutions and subsequent separation of the chelates obtained, by means of high-pressure liquid chromatography. A technique for determining microamounts of palladium in aqueous solutions in the presence of 100-fold ratio of copper and 80-fold ratio of cobalt has been develo...
متن کاملHighly copper(II) ion-selective transport through liquid membrane containing 1-(2-pyridylazo)-2-naphthol.
often an important process in industry and chemical analysis. Liquid-membrane transport in which the extraction and stripping operations are combined in a single process reduces the solvent inventory requirement, and also allows the use of expensive and highly selective extractions, which otherwise would be uneconomic in solvent extractants. For these reasons, liquid-membrane transport has attr...
متن کاملMononuclear and dinuclear Re(I) complexes incorporating 1-(2-pyridylazo)-2-naphthol: synthesis, structure, spectral, DFT and TDDFT studies.
The Re(I) complexes [Re(HPAN)(CO)(3)Cl], 1, and [Re(2)(PAN)(2)(CO)(6)]·C(6)H(12), 2·C(6)H(12), have been prepared by reacting [Re(CO)(5)Cl] with HPAN. Here (PAN)(-) is the deprotonated form of 1-(2-pyridylazo)-2-naphthol. A subsequent reaction of [Re(HPAN)(CO)(3)(CF(3)SO(3))] with a chelating diphosphine ligand generates [Re(PAN)(CO)(P-P)]·CH(2)Cl(2), 3·CH(2)Cl(2). The structures of the complex...
متن کاملPolymer/HIO4 : An efficient catalyst for solvent-free synthesis of 2-naphthol azo dyes
A convenient, one-pot method for the synthesis of diazonium salt has been developed by the sequential diazotization of aromatic amines with NaNO2, polymer- supported periodic acid (PPIA) and 2-naphthole under solvent-free conditions at room temperature. By using this method, several types of aromatic amine, containing electron-withdrawing and electron-donating groups, were rapidly converted to ...
