| 中文摘要: |
| 合成了9,10-二-(2-苄硒基)乙氧基蒽化合物. 并通过1H NMR,13C NMR、能谱和质谱对化合物进行了结构表征,采用荧光光谱及1HNMR滴定法研究了其对汞离子的识别.研究结果表明化合物9,10-二-(2-苄硒基)乙氧基蒽对汞离子具有较强的选择性识别性能,在识别过程中亚甲基的峰位发生了较大变化,同时荧光明显增强,呈现出典型“off-on”荧光化学传感器的特性,其识别机理和应用在进一步研究之中。 |
| 英文摘要: |
| It was synthesised about 9,10-two-(2- Benzylseleno)ethoxy anthracene compound, Which was characterized by Using 1H NMR, 13C NMR, energy spectrum and mass spectrometry, and studied about the recognition of metal ions by fluorescence spectroscopy and 1H NMRStitration method. The results show that 9, 10- two-(2-benzylseleno) ethoxy anthracene compound has Strong recognition ability for mercury ion. It has changed about methylene peak position in the process of recognition and enhanced obviously on its fluorescence at the same time. It was showed the typical fluorescent chemical sensor characteristics about the compound L, Which was discussed about the recognition mechanism and application. |
