Abstract
Tweezer ligands derived from the condensation of 2-hydroxy-5-methyl benzene-1,3-dicarbaldehyde (1) or 2,9-diformyl-1,10-phenanthroline (2) with o-amino benzoic acid were used for the transport of metal ions across liquid membranes. Ligand 1 showed high selectivity for Cu2+ ion and transport was completed over a period of 24 h at a pH value of 1.00. Ligand 2 exhibited selective transport of Pb2+ ion which was completed over a period of 96 h at a pH value of 4.5.
期刊介绍：
Polyhedron publishes original, fundamental, experimental and theoretical work of the highest quality in all the major areas of inorganic chemistry. This includes synthetic chemistry, coordination chemistry, organometallic chemistry, bioinorganic chemistry, and solid-state and materials chemistry.
Papers should be significant pieces of work, and all new compounds must be appropriately characterized. The inclusion of single-crystal X-ray structural data is strongly encouraged, but papers reporting only the X-ray structure determination of a single compound will usually not be considered. Papers on solid-state or materials chemistry will be expected to have a significant molecular chemistry component (such as the synthesis and characterization of the molecular precursors and/or a systematic study of the use of different precursors or reaction conditions) or demonstrate a cutting-edge application (for example inorganic materials for energy applications). Papers dealing only with stability constants are not considered.
