Selective complexation of [small alpha]-amino acids and simple peptides via their carboxylate groups

In contrast to other NiII amino carboxylato or peptide complexes which typically contain five membered NO or NN chelate rings, the macrocyclic complex [Ni2L([small mu ]-Cl)]+ with its cleft-like structure enables a selective carboxylate coordination. The encapsulation of the biomolecules prevents the formation of intermolecular hydrogen bonding interactions, which in turn affects their structures and solubilities.
