Metal-organic frameworks (MOFs) are a class of porous materials of relevance to gas storage, separation science, catalysis, and selective guest binding and release. These frameworks are constructed from inorganic metal cluster nodes and rigid organic linkers. Our research is focused on the preparation of organic linkers that exhibit dramatic influence over the porosity and interpenetration in resultant networks. Specifically, tetragonal organic building blocks are being synthesized to target frameworks with smaller, more dense, pores. On the other extreme, spatial protecting groups are being explored as means of avoiding interpenetration during the synthesis of frameworks with very high porosity. The ability to predictably engineer pore sizes and shapes will allow the encapsulation of guests ranging from the smallest gases (hydrogen) to large organic molecules.
