Synthesis and Structure of a 3-D Metal-Organic Framework, [Cd2(l,4-cyclohexanedicarboxylate)2?DMF], Comprising Unusual TwoDifferent Ligand Conformations

摘要

Metal-organic frameworks (MOFs) which are inorganic and organic hybrid polymeric crystalline solid materials have drawn much attention of many researchers because of wide variety of application of the materials including gas sorption, separation, catalysis, magnetism,sensing, drug delivery and transport. Drastic increase of the number of MOF structures deposited in Cambridge Structure Database (CSD) which is directly related to the number of publications in MOF research field reflects the recent extensive interest in the research of MOFs. Although research interest on MOFs has mainly focused on application of the materials, their rational design principles to construct intriguing architectures and topologies is still important issue in the research of MOFs. Judicious choice of ligands and metal ions and control of their connectivity allow controlling resulting network structure of MOFs and hence physical properties of the resulting materials.
