There are several types of molecular hosts utilized in catalysis: - Cyclodextrins: These are cyclic oligosaccharides that can form inclusion complexes with small molecules. - Calixarenes: These are cup-shaped macrocycles that can host various guest molecules, including ions and organic compounds. - Metal-Organic Frameworks (MOFs): These are porous materials composed of metal ions coordinated to organic ligands, offering large surface areas and tunable pore environments. - Cucurbiturils: These are barrel-shaped molecules that can encapsulate guest molecules, often leading to enhanced catalytic properties.
