【摘要】 采用溶剂热法,以D-樟脑酸(D-H2cam)、2,2’-联吡啶(2,2’-bipy)和Cd2+合成了层状纯手性配位聚合物[Cd2(D-cam)2(2,2’-bipy)2]n(Cd-CP),再用原位合成法引入Tb3+离子,制备出Tb3+@Cd-CP。荧光数据表明,Cd-CP本身的荧光性能较差,而Tb3+@Cd-CP展示出良好的荧光性能。同时,Tb3+@Cd-CP可以通过荧光响应来区分R-和S-丙二醇(R/S-PG),荧光猝灭常数分别为5.3×103和2.0×103L·mol-1,对映选择性因子α为2.65。Tb3+@Cd-CP对R-PG和S-PG的检测限分别为9.3和19.0μmol·L-1,并且表现出良好的可重复性。

【Abstract】 Herein, a layered chiral coordination polymer, [Cd2(D-cam)2(2,2’-bipy)2]n(Cd-CP), was synthesized using a solvothermal method with camphoric acid(D-H2cam), 2,2’-bipyridine(2,2’-bipy) and Cd2+, and Tb3+@Cd-CPwas in-situ synthesized introducing Tb3+ions. The fluorescence experiments revealed that compared to Cd-CP,Tb3+@Cd-CPexhibited ultra-high fluorescence performance. The luminescence sensing performance demonstrated that Tb3+@Cd-CPcould distinguish R/S-propylene glycol(R/S-PG) by fluorescence responses, with fluorescence quenching constant of 5.3×103 and 2.0×103L·mol-1respectively and the enantioselectivity factor(α) of 2.65. Moreover,Tb3+@Cd-CPdemonstrated limits of detection of 9.3 and 19.0 μmol·L-1 for R-PG and S-PG, respectively, and showed good reproducibility.
