Abstract

The lithium and europium(III) cryptates of a macrobicyclic ligand 1 incorporating the 3,3′‐biisoquinoline 2,2′‐dioxide 2 have been prepared. The Eu(III) complex [Eu(2)<sub>2</sub>]Cl<sub>3</sub> has also been obtained. These Eu(III) complexes present characteristic <sup>1</sup>H‐NMR spectra containing markedly shifted resonances. They are strongly luminescent; the emission spectra, quantum yields, and lifetimes have been determined. Copyright © 1990 Verlag GmbH & Co. KGaA, Weinheim
