The rapidly expanding field of metal organic framework (MOF) materials, or porous coordination polymers (PCPs), is evidenced from the exponential growth with respect to the number of scientific publications reported and the accompanying new materials discovered over the past decade.MOFs are crystalline hybrid materials constructed from inorganic and organic building blocks, via the fundamental process of self-assembly at the molecular level. The resulting nanoporous materials encompass a myriad of 3D open-framework structures (e.g.Fig. 1), which feature vast chemical and structural diversity.
