A mini review on applications of pyrazole ligands in coordination compounds and metal organic frameworks

The fastest growing class of materials in chemistry is that of the metal organic frameworks (MOF’s), consisting of metal nodes and organic linkers as building units. There exist numerous inorganic ligands to coordinate with metal ions but certainly various organic linkers are also available. Amongst the broadly available heterocyclic compounds, pyrazole functionalities have achieved greater attention owing to their wide-ranging applications. Recently, applications of pyrazole ligands in coordination compounds and structured porous materials such as metal organic frameworks have undoubtedly created considerable interest in developing newer frameworks. Utility of these hybrid compounds in adsorption, fluorescent and colorimetric analysis, drug delivery, catalysis and sensing/detection of analyte are receiving significant interest. Reference to the enormous background on the synthesis and biological resourcefulness of pyrazoles, this review proposes a brief survey on applications of pyrazole ligands in coordination compounds and metal organic frameworks.
