| 摘要: 设计合成了一种基于偶氮苯基团的简单而高效的比色探针L1,并利用紫外-可见吸收光谱考察其对阴离子(F-, Cl-, Br-, I-, AcO-, H2PO4-, HSO4-, ClO4-和CN-)的识别性能。结果表明:探针L1在DMSO/H2O(5:5, V/V)的含水体系中,可以实现对CN-单一选择性识别;且加入CN-时,溶液颜色立刻由无色变为红色,而加入其它阴离子则无变化,说明该探针能够实现对CN-的裸眼识别。另外,该探针对CN-的检测灵敏度较高,最低检测限达到了1.3 μmol·L-1。此外,我们制作了负载有探针分子L1的试纸条,能够更加方便快捷的检测CN-。 |

| Abstract: A colorimetric probe L1 bearing azosalicylic aldehyde of benzoyl hydrazone was synthesized. The binding property of the sensor with anions, such as F-, Cl-, Br-, I-, CH3COO-, H2PO4-, HSO4-, ClO4-and CN-, was examined by UV-Vis spectroscopy. The result showed probe L1 had a single selectivity colorimetric recognition for CN-in DMSO/H2O (5:5, V/V) binary solutions. When CN-was added to the solution of L1, a dramatic color change from colorless to red was observed, while the other anions did not cause noticeable changes, which indicates that the probe could detect CN-by naked eyes. The detection limit for CN-was 1.3 μmol·L-1 by UV-Vis spectroscopy. Furthermore, test strips based on sensor L1 was fabricated. |
