Two luminescent coordination polymers (CPs), {[Cd2L2(H2O)4]·H2O}n (1) and {[Zn2L2(H2O)4]·H2O}n (2) (H2L = 5-(1H-1,2,4-triazol-1-yl)isophthalic acid) are reported herein. The CPs reveal readily dispersible two-dimensional (2D) layer structures with considerable stability in aqueous media within a wide pH range (pH = 2-12). Sensing experiments indicate that they can serve as highly selective and sensitive fluorescent probes toward CrVI-anions (CrO42- and Cr2O72-).
本文报道了两个发光配位聚合物（CPs），{[Cd2L2(H2O)4]·H2O}n（1）和{[Zn2L2(H2O)4]·H2O}n（2）（H2L = 5-（1H-1,2,4-三唑-1-基）间苯二甲酸）。这些 CP 呈现出易于分散的二维（2D）层状结构，在很宽的 pH 范围内（pH = 2-12）在水介质中具有相当的稳定性。传感实验表明，它们可以作为高选择性和高灵敏度的荧光探针，用于检测六价铬阴离子（CrO42-和 Cr2O72-）。
