将meso-四(4-N,N,N-三甲基氨基苯基)卟啉(TTMAPP)组装到介孔分子筛MCM-41的孔道中,制备了金属离子传感材料TTMAPP/MCM-41.X射线粉末衍射证明,组装后MCM-41的有序孔道结构未发生变化.紫外可见吸收光谱结果表明,组装体具有典型的卟啉吸收特性.锌离子的引入会使TTMAPP/MCM-41的荧光光谱在600nm处产生一个新发射峰,而金属铜离子可以使TTMAPP/MCM-41的发光产生猝灭,猝灭程度可达到68.42%.实验结果表明TTMAPP/MCM-41对于金属离子具有良好的传感特性.
The meso-tetrakis (4-N, N, N-trimethylaminophenyl) porphyrin (TTMAPP) was assembled into the pore of mesoporous MCM-41 to prepare metal ion sensing material TTMAPP / MCM-41. X-ray powder diffraction confirmed that there was no change in the ordered pore structure of MCM-41 after assembly.Ultraviolet-visible absorption spectroscopy results showed that the assembly possessed typical porphyrin absorption characteristics.The incorporation of zinc ions led to the fluorescence of TTMAPP / MCM-41 The spectrum produced a new emission peak at 600 nm, and Cu2 + could quench the luminescence of TTMAPP / MCM-41 with a quenching degree of 68.42%. The experimental results show that TTMAPP / MCM-41 has a good emission of metal ions Feeling characteristics.
