Metal ion templating in a sol–gel synthesis is used to develop multiligand 8-hydroxyquinoline binding sites in porous silica structures. The acid–base equilibria and the metal ion binding equilibria and stoichiometry of these materials are investigated by in situ Raman spectroscopy. This technique is capable of resolving spectral responses of the free ligand and its acid–base forms along the monomeric and dimeric ligand complexes with Cu²⁺. The proton-transfer equilibrium constants and first ligand binding equilibrium constant to Cu²⁺ for the metal ion-templated silica are equivalent to surface-immobilized 8HQ on silica gel. The second ligand binding constant to Cu²⁺, however, is comparable to the first ligand binding constant, which differs from free-solution behavior, where an order of magnitude smaller value is expected. The free energy available for binding the second ligand within the templated material is comparable to the first ligand, probably due to the nearly optimal location of the second ligand for binding, based on the templating that is done during this synthesis. Furthermore, the metal ion concentration responses of sol–gels prepared with varying amounts of metal ion during the syntheses were also tested, and the results indicate control over the fraction of templated binding sites.
