摘　　要：设计合成了受体分子[[4-[(硫代碳酰氨基)氨甲基]苄基]氨基]硫脲-Gd(Ⅲ)配合物(LH-GdⅢ),研究了其UV-Vis吸收光谱对阴离子的响应.发现受体的DMSO溶液中加入F-后,吸收光谱强度发生极大变化,并于426 nm处产生新的吸收峰,且观察到清晰的等吸收点.研究表明氟离子以1∶1结合模式影响体系的吸收,该受体分子可作为潜在裸眼识别阴离子传感器.The compound 2,2＇-（1,4-phenylenebis（methylene）） bis（hydrazinecarbothioamide） was synthe-sized and its complex with gadolinium was studied as an anion receptor.The binding properties of the re-ceptor with anions were investigated by UV-Vis spectroscopy.The absorption spectra of the receptor in DMSO in the presence of F-underwent substantial changes,with appearing a new band at 426 nm and a clear isosbestic point.The UV-Vis spectroscopic titration experiments indicated the formation of 1∶1 com-plex between the receptor and F-.The receptor holds promise to be used as an optical chemosensor with naked-eyes.
