Construction of a New ZnII Coordination Polymer for Selective Fluorescence Sensing of CCl4

Solvothermal reactions of Zn(NO3)(2)center dot 6H(2)O, H(3)tci, and biimpy generated a new Zn-II coordination polymer namely [Zn-3(tci)(2)(biimpy)](n)center dot 2n(DMF) (1 H(3)tci = tri(2-carboxyethyl) isocyanurate, biimpy = 2,6-bis(1-imdazoly) pyridine, DMF = N, N-dimethylformamide). Single-Crystal X-ray diffraction analysis reveals that compound 1 features a 2-fold interpenetrated 3D pillar-layered framework based on trinuclear [Zn-3(COO)(6)] cluster subunits. Topological analysis reveals that compound 1 represents a 2-fold interpenetrated (3,8)-connected tfz-d topological network with the point symbol of {4(3)}(2){4(6).6(18).8(4)}. The luminescence properties of compound 1 dispersed in different organic solvents were systematically investigated. The results indicated that compound 1 can be used as a candidate for selective sensing of CCl4 via a luminescence quenching mechanism.
