【摘要】 以2,5二甲氧基对苯二甲醛和2,4,6-三（4-氨基苯基）-1,3,5-三嗪为原料，通过溶剂热法制备出亚胺类共价有机框架材料DmaTAPT。采用X-射线粉末衍射、C¹³固体核磁等方法对其结构进行表征，考察其在荧光检测Al³⁺中的应用并对检测机制进行研究。结果表明，基于光生电子转移荧光增强机制，对Al³⁺检测限为1.82×10^-5mol/L，可以作为荧光传感器实现对Al³⁺的高效检测。更多还原

【Abstract】 A novel covalent organic framework material was prepared through solvothermal method with 2, 5 dimethoxy-p-phenyldiformaldehyde and 2, 4, 6-tri（4-aminophenyl）-1, 3, 5-triazine as raw materials. X-ray powder diffraction and C¹³ solid nuclear magnetism was used to characterize the structure of Dma-TAPT. Then, the COFs were applied to detect Al³⁺ through fluorescence enhancement method and the corresponding sensing mechanism was investigated. The results showed that the detection limit for Al³⁺ was 1.82×10^-5 mol/L and the mechanism was based on the photogenic electron transfer. Dma-TAPT can be used as a fluorescence sensor to realize efficient detection of Al³⁺.更多还原
