摘要：
Herein, a layered chiral coordination polymer, [Cd-2(D-cam)(2)(2,2' -bipy)(2)](n) (Cd-CP), was synthesized using a solvothermal method with camphoric acid (D-H(2)cam), 2,2'-bipyridine (2,2'-bipy) and Cd2+, and Tb3+@Cd-CP was in-situ synthesized introducing Tb3+ ions. The fluorescence experiments revealed that compared to Cd-CP, Tb3+@ Cd-CP exhibited ultra-high fluorescence performance. The luminescence sensing performance demonstrated that Tb3+@Cd-CP could distinguish R/S-propylene glycol (R/S-PG) by fluorescence responses, with fluorescence quenching constant of 5.3x10(3) and 2.0x10(3) L center dot mol(-1) respectively and the enantioselectivity factor (a) of 2.65. Moreover, Tb3+@Cd-CP demonstrated limits of detection of 9.3 and 19.0 mu mol center dot L-1 for R-PG and S-PG, respectively, and showed good reproducibility.
