It is challenging and vital to develop coordination polymers (CPs) with an outstanding sensing performance. In this work, CP-based sensors active S N sites are first exploited. Three new Cu-CPs [Cu(L)(SCN)2·2DMF]n (1), [Cu(L)(SCN)·2DMF]n (2), [Cu(L)(CN)·2DMF]n (3) were successfully synthesized by 9,10-bis(di(pyrimidin-5-yl)methylene)-9,10-dihydroanthracene (L) SCN-/CN- ligands. 1 demonstrates a 1D wavelike chain, fabricated L bridges linking Cu(SCN)2 units. 2 exhibits 2D (3,3)-connected network SCN-, 3-connected L, Cu 3 3D framework, built 4-connected centers, CN-, bridges. 1-3 have good water, pH, thermal stabilities. uncoordinated can detect Hg2+ through the fluorescence enhancing ("turn-on") effect. Meanwhile, only has shows negative ability. ultrahigh sensitivity selectivity. The KSV LOD of toward about 5 times superior those 2, separately. represent S- N-rich exhibit excellent "turn-on" capacity. Their mechanism difference performances discussed in detail.
