Assembly of unique interpenetrated metal–organic frameworks based on flexible tetra-carboxylate ligands
Entangled metal–organic frameworks (MOFs) are attracting more and more attentions attributed to their special performances, such as adsorption, fluorescence and catalysis. It is still of significant to synthesize new MOF with unique interpenetrating motif. In this work, two new MOFs, namely [(Me2)NH2]·[In(TCM)]·4DMF (JOU-32), and [Cd2(TCM)(DMF)2]·5DMF (JOU-33), have been successfully synthesized using flexible tetra-carboxylate ligand tetrakis(4-carboxyphenoxymethyl)methane (H4TCM). The structures of JOU-32 and JOU-33 were well characterized by single-crystal X-ray diffraction. It is shown that JOU-32 reveals a rare example of interpenetrating MOF with two different networks disorderedly distributed within the same crystal. JOU-33 is a (4,8)-connected flu topological structure based on [Cd4(COO)8(DMF)2] cluster. The fluorescent properties for both JOU-32 and JOU-33 have also been tested. The average life times for JOU-32 and JOU-33 were detected to be 2.39 and 2.42 ns, respectively. In addition, both JOU-32 and JOU-33 can be utilized as fluorescent probes for detection of NB. This work provides valuable clues for preparing new fluorescent MOFs with attractive structures.
期刊介绍：
Polyhedron publishes original, fundamental, experimental and theoretical work of the highest quality in all the major areas of inorganic chemistry. This includes synthetic chemistry, coordination chemistry, organometallic chemistry, bioinorganic chemistry, and solid-state and materials chemistry.
Papers should be significant pieces of work, and all new compounds must be appropriately characterized. The inclusion of single-crystal X-ray structural data is strongly encouraged, but papers reporting only the X-ray structure determination of a single compound will usually not be considered. Papers on solid-state or materials chemistry will be expected to have a significant molecular chemistry component (such as the synthesis and characterization of the molecular precursors and/or a systematic study of the use of different precursors or reaction conditions) or demonstrate a cutting-edge application (for example inorganic materials for energy applications). Papers dealing only with stability constants are not considered.
