An all-inorganic heterobinuclear chromophore consisting of Ti(IV) oxo-bridged to a Mn(II) center has been assembled on the surface of silica pores of MCM-41 material. The key step of covalent attachment on the pore surface is the reaction of a Mn(II) precursor featuring weakly held CH3CN ligands with the OH group of a previously anchored titanol site. The optical diffuse reflectance spectrum re...

macrocyclic heterobinuclear zn(ii)–cu(ii) complexes with phenol based dicompartmental ligands possessing contiguous hexa- and penta-coordination sites were prepared by a stepwise procedure. the ligands include similar n4o2 and dissimilar n(imine)3o2 and n(amine)3o2 coordination sites sharing two phenolic oxygen atoms. the six-coordination site comprises two pyridyl pendant arms on the amine nit...

Much progress has been made in designing metalloproteins with structures similar to native enzymes and advances in computational biology have allowed for rational design of enzyme function as well. Despite these achievements, most designed enzymes have simple active site structures and low activities, with limited turnover numbers. Designing artificial enzymes with higher complexity and number ...
