Hybrid inorganic-organic frameworks are a new class of materials which continue to attract much attention due to their diverse structures and the wide range of associated properties. These compounds, which are also known as metal-organic frameworks (MOFs) or coordination polymers, have been studied for a variety of potential applications including gas storage, separation, catalysis, conductivity, luminescence, magnetism and drug delivery. Though many of the emerging properties of MOFs are associated with the higher dimensionalities of their frameworks, the basic properties can also be controlled by the chemistry of the underlying coordination unit. Indeed, MOFs themselves emerged from conventional coordination chemistry. In this talk i shall discuss synthesis and properties of some of the fascinating MOFs both from my own research and the literature, emphasizing the structure-property relationship.
