摘　　要：在溶剂热条件下,成功合成了一种稳定的配位聚合物[Cd_(2)(L)(bpb)(H_(2)O)_(4)]·0.5H_(4)L(1)(H_(4)L=1,1'-乙烷基联苯-3,3',5,5'-四羧酸,bpb=1,4-二(4-吡啶基)苯)。1在不同的有机溶剂和水中表现出优异的稳定性。1可通过荧光猝灭检测水中的罗红霉素(ROX)和B_(4)O_(7)^(2-),检测限分别为0.21和1.59μmol·L^(-1)。1可成功用于延河水中ROX和B_(4)O_(7)^(2-)的测定。此外,分析讨论了其传感机理。A stable coordination polymer,[Cd_(2)(L)(bpb)(H_(2)O)_(4)]·0.5H_(4)L(1)(H_(4)L=1,1'‑ethylbiphenyl‑3,3',5,5'‑tetracarboxylic acid,bpb=1,4‑di(pyridin‑4‑yl)benzene),were successfully constructed under solvothermal conditions.1 exhibited excellent stability in different organic solvents and water.1 could detect roxithromycin(ROX)and B_(4)O_(7)^(2-) in water by fluorescence quenching,and the detection limits were 0.21 and 1.59μmol·L^(-1),respectively.1 could be successfully used for the determination of ROX and B_(4)O_(7)^(2-) in Yanhe River water.Moreover,the possible sensing mechanisms are also discussed in detail.
