Abstract

Earlier we reported the tendency of ferrocenylmethyl substituted amino acids to organize around Cu(II) in a C2 symmetry. In this paper we have utilized this property to form a chiral cavity using a L-tyrosine derivative. Structural characterization of [CuII(S-fTyr)2(MeCN)2] (1), where S-fTyr1− is ferrocenylmethyl-L-tyrosinate, showed that the alignment of two tyrosine aromatic rings around the fifth coordination site generates a narrow cavity. Structural characterization of [Cu(S-fTyr)2(pyrazine)] (2), [Cu(S-fTyr)2(pyridine)] (3), [Cu(S-fTyr)2(bpy)] (4) and [Cu(S-fTyr)2(H2O)] (5) revealed that planar heterocyclic N-donors as guests stabilized the cavity, while polar water molecules destroyed it. Electrochemical properties of the complexes showed a shift of CuII/CuI potentials depending on the strength of the guest binding inside the cavity.
