| Abstract: | Two 1-D luminescent metal-organic frameworks with identical structures, {[Mn(BBPTZ)2(MeCN)2]·(ClO4)2}n (1) and {[Zn(BBPTZ)2(MeCN)2]·(MeCN)2·(ClO4)2}n (2), have been synthesized under solvent diffusion evaporation and characterized by elemental analyses, thermal analyses and single-crystal X-ray diffraction. Both complexes crystallize in the monoclinic system, space group C2/c with six-coordinate M(II). Thermal decompositions of the complexes have been studied using thermogravimetric analyses (TGA). The complexes exhibit a significant fluorescence quenching effect to Fe3+ in acetonitrile solution. The LoDs (Limit of Detection) of the complexes to Fe3+ are 2.59 × 10?8 M and 1.57 × 10?8 M for 1 and 2, respectively. The complexes could be applied to efficient chemosensor for Fe3+ detection. |
