Abstract
Supported catalysts include a solid support, a metal-ligand complex tethered to a surface of the solid support through at least two surface reactive moieties of the metal-ligand complex, and a conformationally stable molecular pore defined between the metal-ligand complex and the surface of the solid support. The metal-ligand complex includes a catalytic metal center, such as a transition metal, coordinated with multiple monodentate ligands, a multidentate ligand, or a combination thereof. The ligands include a tethering portion that is terminated by a surface reactive moiety tethered to the surface of the solid support by a surface interaction. By tailoring the tethering portion, a volume of the molecular pore may be provided that is selective and suitable for a chosen reactant or a chosen reaction type.
