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) 2 ]Cl 3 has also been obtained. These Eu(III) complexes present characteristic 1 H‐NMR spectra containing markedly shifted resonances. They are strongly luminescent; the emission spectra, quantum yields, and lifetimes have been determined.
