摘要：

The assembly of a N-containing heterocyclic dicarboxyl rigid ligand with a cadmium ion resulted in the formation of a 2D coordination polymer {[Cd(PYIA)(H2O)]center dot H2O}(n) (H(2)PYIA = 5-(2H-Pyrazol-3-yl)-isophthalic acid) (SUF-1). The compound SUF-1 determined by single crystal X-ray diffraction showed a 2D double layer plane structure containing a six-coordinated Cd2+ bimetallic cluster. SUF-1 was highly stable and strongly emitted blue light in water at ambient temperature. Significantly, it exhibited excellent selectivity and highly sensitivity detective of Fe3+ and 2,4,6-trinitrophenol with a fluorescence quenching mechanism in water. (C) 2017 Elsevier B.V.
