Abstract
A 104‐ to 105‐times more intense absorption than the corresponding aqua complexes is exhibited by the cryptates 1 and 2; in the latter the ligand absorbs, in the former the metal ion. From the luminescence‐lifetimes in H2O and D2O it can be deduced that in Eu aq3⊕ nine or ten H2O molecules coordinate the Eu3⊕ ion, whereas in 1 only two or three H2O molecules coordinate. Even in 10‐5 molar aqueous solutions, 1 and 2 can absorb 1% of the incident UV photons and emit them again as visible light. (Figure Presented.)
