Thermodynamics of binding of carboxylates to amphiphilic Eu(3+)/Cu(2+) metallacrown.
The binding constants of acetate and benzoate to a Pheha-based 15-metallacrown-5 have been determined by a fluorimetric indicator displacement assay demonstrating on a thermodynamic basis the stabilization effect arising from complexation of the less polar carboxylate into the hydrophobic pocket of the metallacrown scaffold.
