Abstract
The perturbation of the racemic equilibrium of luminescent D3 terbium(III) complexes with chelidamic acid (CDA), a hydroxylated derivative of 2,6‐pyridine‐dicarboxylic acid (DPA), by added chiral biomolecules such as L‐amino acids has been studied using circularly polarized luminescence and 13C NMR spectroscopy. It is shown in this work that the chiral‐induced equilibrium shift of [Tb(CDA)3]6− by L‐amino acids (i.e. L‐proline or L‐arginine) was largely influenced by the hydrogen‐bonding networks formed between the ligand interface of racemic [Tb(CDA)3]6− and these added chiral agents. The capping of potential hydrogen‐bonding sites by acetylation in L‐proline led to a ∼100‐fold drop in the induced optical activity of the [Tb(CDA)3]6−:N‐acetyl‐L‐proline system. This result suggested that the hydrogen‐bonding networks serve as the basis for further noncovalent discriminatory interactions between racemic [Tb(CDA)3]6− and added L‐amino acids.
