Tweezerligands 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 metalions 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 selectivetransport of Pb2+ ion
