| 摘 要： | 设计合成含2-硫代海因的小分子对照物1和聚苯撑乙炔poly(1)。通过一系列阴离子的正四丁基铵盐的DMSO溶液来评价聚合物的阴离子识别性能。加入F-后,poly(1)的DMSO溶液荧光淬灭;然而,加入Cl-,Br-,HSO-4,NO-3和CH3CO-2后,poly(1)溶液荧光不变,说明poly(1)对氟离子有荧光识别能力。Poly(1)对F-的Stern-Volmer淬灭常数为7.09×104M-1,相应地,对照物1对F-的Stern-Volmer淬灭常数为5.10×102M-1,说明了poly(1)具有增强淬灭效应。

| Abstract: | Novel of small molecule counterpart and poly （phenyleneethynylenes）（1） bearing 2-thiohydantoin were synthesized.The anion sensing ability of poly （ 1 ） were estimated via the tetra -n-butylammonium （ TBA ） salts of a series of anions in DMSO.The addition of F -quenches the fluorescence , the fluorescence of the solution only changed slightly upon adding other anions of Cl -, Br-, HSO4-, NO3-and CH3CO2-, indicating the sensing ability of poly （1） towards F -.The Stern-Volmer quenching constant of poly （1） causes by F -was 7.09 ×104 M-1 , while that of the small molecule counterpart was 5.10 ×102 M-1 , indicating the amplified quenching effect of poly （1）. |
