Background

The design, synthesis, characterization, and application of porous materials has broadly attracted both scientists and engineers due to the need to understand and control reactions or processes that occur in nanometer-sized spaces. This has a profound commercial impact because porous solids are widely used as sorbents in important applications such as molecule storage, separation and heterogeneous catalysis. Progress in the area of hybrid inorganic-organic materials has lead to the development of coordination compounds that now extend in 1-, 2-, or 3-dimensions. The term coordination polymer has been used to describe such compounds in which the backbones or frameworks of these materials are made by connecting metal ions or metal clusters (referred to as vertices of the framework) with organic ligands that when bridging multiple metal centers are commonly referred to as linkers or links. To date, only a few examples of crystalline mesoporous coordination polymers have been reported.

Technology

Researchers at the University of Michigan have developed a crystalline coordination polymer, wherein multiple polytopic organic molecules are assembled to produce porous framework materials. The pore dimensions achievable are in micro- and mesoporous range. In addition, the invention provides as simple procedure for controlling the type of functionality and its concentration within a porous crystal. Production of these materials involves the use of 2 or more linkers, which may be of differing geometries, containing 2 or more sites of a metal to bind in combination with at least one metal ion or metal cluster to generate a material with two or more linkers spanning vertices in the framework.
