Abstract

Cooperative interactions between metal ions and bivalent tryptophan side chain are identified in water by fluorescence quenching of a designed novel receptor, EDTA-bis(L-tryptophan methyl ester), supplemented by a circular dichroism study; results revealed that the receptor is capable of distinguishing a variety of metal ions on the basis of their abilities in quenching tryptophan fluorescence and the relative magnitude of these interactions is Cu2+ ∼ Fe2+ >> Co2+ > Ni2+ >> Mn2+ > Zn2+ > La3+ > Al3+.
