Abstract

A series of bimetallic lanthanide complexes was prepared from a bimacrocyclic system in which two DO3A units are linked by a m-xylyl unit appended with either a NO(2) or an NH(2) group (DO3A = 1,4,7,10-tetraazacyclododecane-1,4,7-triacetic acid). The Nd-, Eu-, Th- and Yb-complexes were all luminescent: time-resolved studies indicated that the lipophilic xylyl group restricts close approach of H(2)O to the metal centre.
