A new 3D supermolecular coordination polymer [Mg(H2TPTC)(2)center dot 2H(2)O](n) (1) was synthesized under solvothermal condition by a rigid rich electronic ligand H4TPTC ([1:1':4',1 ''-terphengl]-3,3 '',5,5 ''-tetracarboxylic) and Mg(II) ion. Complex 1 presents an excellent fluorescent Mg-MOF sensor for highly sensitive and selective detecting TNP, the K-sv is up to 3.869 x 10(4)M(-1) . Furthermore, complex 1 can be quickly regenerated by simple washing with acetonitrile, exhibiting good recyclability for detecting TNP. The quench mechanisms of complex 1 for sensing nitro aromatic explosives were studied as well.
