Researchers Report Metal-organic Frameworks Based on Flexible Ligands
Apr 21, 2014 Email"> PrintText Size
Metal-organic frameworks (MOFs) are emerging as an important family of porous materials not only because of their intriguing network topologies but also exploitable properties for potential applications such as gas adsorption and separation, catalysis, luminescence, sensing, proton conduction and etc. Their crystalline nature, high and permanent porosity, uniform pore sizes, extraordinary surface areas, finely tunable pore surface properties, and potential scalability to industrial scale have made these materials an attractive target for further study.
Recently, the research group headed by Prof. CAO Rong at Fujian Institute of Research on the Structure of Matter, Chinese Academy of Sciences, reported metal-organic frameworks based on flexible ligands (FL-MOFs) in Chemical Society Review (doi: 10.1039/C3CS60483G).
In this review, the potential advantages and disadvantages of the use of flexible ligands to construct MOFs was discussed. Emphasis has been placed on the design and the structural diversity of FL-MOFs. Homochiral FL-MOFs and dynamic frameworks induced by flexible ligands are also briefly outlined. An overview is also shown to the applications of FL-MOFs as platforms for gas adsorption, heterogeneous catalysis, proton conduction etc.
Previously, Prof. CAO's group had made a series of relevant progress on the controlled synthesis and applications of FL-MOFs. For instance, based on flexible ligands tetrakis[4-(carboxyphenyl)oxamethyl]methane acid (H4tcm) or tetrakis[(3,5-dicarboxyphenoxy)methyl]methane (H8tdm), they had synthesized a series of porous FL-MOFs with diverse topologies and employed them as platforms for gas adsorption and separation, non-linear optical (NLO) and ferroelectric properties etc. (J. Am. Chem. Soc. 2009, 131, 6894-6895; Chem.-Eur. J. 2012, 18, 7896-7902; Chem. Commun. 2010, 46, 8439-8441; Chem. Commun. 2011, 47, 3766-3768; Inorg. Chem. 2011, 50, 2264-2271; Inorg. Chem. 2013, 52, 3127-3132.)
