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

Abstract

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.
