Abstract
Four diastereomers of DELTA-[Co(trans-1,2-cyclohexanediamine)3]3+ are examined as enantioselective excited-state quenchers of chiral Eu(dpa) 3(3-) and Tb(dpa)3(3-) luminophores (dpa=dipicolinate dianion) in solu tion. In their quenching actions, all four diastereomers can distingui sh between and interact differentially with the LAMBDA and DELTA enant iomers of the luminophores, but their enantiomeric preferences show in teresting variations that may be correlated with chelate-ring conforma tional structure.
