Synthesis of homodinuclear macrocyclic complexes of lanthanides and phenolic schiff bases
TL;DR: The first homodinuclear macrocyclic lanthanide complexes were obtained as compounds of the 2:2 Schiff base formed by condensing 2,6-diformyl-p-cresol and triethylenetetramine (L7) by a template procedure using lanthanides nitrates and perchlorates.
