Abstract
A new aza-thia macrocycle compound was obtained with high dilution reaction. A new zinc(II) phthalocyanine containing four 17-membered macrocycle moieties with nitrogen-sulfur donor atoms was synthesized in a multi-step reaction sequence. Zn(II) phthalocyanine (S4N-ZnPc) and all of the new compounds were characterized by elemental analysis and different spectroscopic methods such as 1H NMR, 13C NMR, IR, UV–vis and mass. Obtained macrocyclic compounds 6 and S4N-ZnPc were used in solvent extraction of metals such as Ag+, Hg2+, Cd2+, Zn2+, Cu2+, Ni2+, Pb2+ and Cr3+ from aqueous phase to the organic phase. The results of two-phase extraction studies on new macrocyclic compounds showed very high selectivity for silver ions compared to other metal cations.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
