Preparation and study of an f,f,f ',f '' covalently linked tetranuclear hetero-trimetallic complex - a europium, terbium, dysprosium triad

A heterotrimetallic tetranuclear lanthanide complex containing two dysprosium ions, a terbium ion and a europium ion has been prepared by coupling three kinetically stable complexes together using the Ugi reaction. The covalently linked trimetallic system exhibits luminescence from all the different lanthanide centres.
