Abstract

A novel inclusion complexes nanofibrous membrane fluorescent sensor was prepared for recognizing F- via electrospinning and host–guest interaction. The host α-cyclodextrin on the surface of the electrospun nanofiber membrane is assembled into the guest azobenzene molecule which modified with F- fluorescent probe,and the formation of the inclusion complex is fixed on the surface of the nanofibrous membrane without external force,to prepare a novel surface controllable composite nanofiber membrane for F- detection. The inclusion complexes nanofibrous membrane exhibited favourable sensitivity and selectivity for F-. The introduction of F- would result in notable fluorescent decreasing of the membrane, but the other most common anions would not disturb the detection of F-. Moreover, this nanofibrous membrane was not only a fluorescent sensor for detecting F-, but also a good adsorbent for F- in solution.

静电纺丝与主-客体相互作用制备氟离子纳米纤维膜荧光传感器
利用静电纺丝和主-客体相互作用制备了一种新型包合物纳米纤维膜荧光传感器。将电纺丝纳米纤维膜表面的宿主α-环糊精组装成用F-荧光探针修饰的客体偶氮苯分子,并将形成的包合物不受外力固定在纳米纤维膜表面,制备了一种用于F-检测的新型表面可控复合纳米纤维膜。包合物纳米纤维膜对F-具有良好的敏感性和选择性。F-的引入会导致膜的荧光明显下降,但其他最常见的阴离子不会干扰F-的检测。此外,该纳米纤维膜不仅是检测F-的荧光传感器,而且是F- in溶液的良好吸附剂。关键词:主-客体相互作用,纳米纤维膜,荧光传感器,氟离子,吸附剂
