摘要：
A znic fluorescence framework {[(Zn-2(BDPO)center dot 3H(2)O]center dot H2O}(n) (1) (H4BDPO = N,N'-Bis(3,5-discarboxyphenyl)oxalamide) was successfully synthesized and characterized. Complex 1 is a 2D sheet [Zn-2(BDPO)](n) the H-bondings and pi center dot center dot center dot pi interactions extend the 2D sheet into 3D supermolecular framework. Importantly, it is a rarely reported highly selective and sensitive luminescence MOF sensor for detecting 2,4,6-Trinitroluene(TNT) and Fe(III) simultaneously through fluorescence quenching. Furthermore, the sensing mechanisms are mainly attributed to the photo-induced electron transfer and competitive absorptions between the excitation/emission of 1 and analytes.
