Emerging as a new type of functional materials, metal-organic frameworks (MOFs) have attracted widespread research interests in the past decade.  MOFs are crystalline inorganic-organic hybrids, and are constructed of metal atoms or small metal-containing clusters (known as secondary building units (SBUs)) connected by multidentate organic ligands via coordination bonds.  Through the judicious selection of the metal ions or SBUs and organic linkers, they are not only be rationally designed with a variety of topologies, but also be systematically functionalized with specific characteristics such as high surface area, uniform but tunable pore size, functionalizable pore walls, and intriguing framework flexibility etc.  These characteristics have offered MOFs great potential in hydrogen storage, methane storage, gas separation, photoluminescence, and magnetism applications, and also promise their future applications in photocatalysis, solar energy conversion, fuel cells, drug delivery, enzyme crystallography, biosensing and biolabelling etc.
