文摘The enantiomers of carboline-based cryptates were successfully resolved by chiral HPLC.These complexes show high configurational stability under harsh conditions and their absolute configuration was determined by comparing theoretical and expe rimental electronic circular dichroism spectra.The e nantiopure cryptates exhibit strong circularly polarized luminescence with a maximum dissymmetry factor glum=0.25 for the f-f transition 5 D0→7 F1(λ=594 nm)under visible light excitation atλgx=400 nm.
