POLY-OXA-AZA RECEPTORS OF THE PENDANT ARM TYPE AND THEIR LN (III) COMPLEXES, A METHOD FOR THE PRODUCTION THEREOF AND APPLICATION OF SAME TO DEVICES AS ION FLUOROSENSORS IN AQUEOUS SOLUTION.

摘要

The present invention relates to a novel poly-oxa-aza cyclic receptor of the type containing 2,6-bis [ 2-(1, 3-diamine-2-azaethyl-2-formyl-phenoxymethyl ] pyridine, L3 imine ligand, as well as the Eu(III) and Tb (III) complexes thereof, a process for obtaining the same through Schiff base-type condensation of a the precursor 2,6-bis (2-formyl-phenoxymethyl ) pyridine and an aliphatic amine using 1,3-diamino-2-propanol (DP). The ligand-binding capacity for Cu(II), Cr(III), Cd(II) and Zn(II) of the isolated compounds was assayed.
