Electronic Pre-Activation of -COOH Ligands by O-H···O in Natural Deep Eutectic Solvents for Enhanced Rare-Earth Coordination: A Quantum-Chemical Study.
Natural deep eutectic solvents (NaDESs) are commonly regarded as passive solvation media. However, their local hydrogen bonds may act as electronically structured environments that can perturb embedded ligands. Herein, using quantum-chemical analysis, finite-cluster calculations suggest that selected O-H···O motifs can...
