Three metal organic frameworks based on mixed ligands: synthesis, crystal structures and luminescent sensing of nitro explosives
Three new metal organic frameworks [Zn(bipa)(suc)]n (1), [Ni(bipa)(suc)(H2O)2]n (2) and [Co(bipa)1.5(oip)(H2O)]n (3) (bipa = 2,5-bis(1-imidazole)pyrazine), H2suc = succinic acid, H2oip = 5-hydroxy isophthalic acid) have been synthesized by solvothermal method. They were then characterized by single crystal X-ray diffraction, elemental analysis, infrared spectrum and thermogravimetric analysis. Structural analyses showed that MOFs 1 and 3 exhibited a 3D supramolecular network, while MOF 2 presented a 2D layered structure and was further assembled to a 3D architecture via intermolecular O–H···O hydrogen bond. Moreover, the luminescence sensing of MOF 1 toward nitro explosives was investigated, owing to its excellent chemical stability and luminescence properties. MOF 1 showed remarkable fluorescence quenching toward TNP with a high Ksv value of 6.48 × 104 M−1 and a low limit of detection of 1.4 × 10−5 M. Also, the luminescent sensing mechanism of MOF 1 was investigated.
期刊介绍：
Transition Metal Chemistry is an international journal designed to deal with all aspects of the subject embodied in the title: the preparation of transition metal-based molecular compounds of all kinds (including complexes of the Group 12 elements), their structural, physical, kinetic, catalytic and biological properties, their use in chemical synthesis as well as their application in the widest context, their role in naturally occurring systems etc.
Manuscripts submitted to the journal should be of broad appeal to the readership and for this reason, papers which are confined to more specialised studies such as the measurement of solution phase equilibria or thermal decomposition studies, or papers which include extensive material on f-block elements, or papers dealing with non-molecular materials, will not normally be considered for publication. Work describing new ligands or coordination geometries must provide sufficient evidence for the confident assignment of structural formulae; this will usually take the form of one or more X-ray crystal structures.
