摘要
将5,12-二[6(2氨基乙基氨基)己基]喹吖啶酮(BAEAHQA)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BEDAHQA/MCM-41.荧光光谱显示组装体的发光避免了喹吖啶酮固体发光的浓度猝灭现象.引入不同的金属离子将使BAEAHQA/MCM41的荧光光谱强度发生不同程度的降低和峰位移动.尤其是金属钴离子可以使BAEAHQA/MCM-41的发光产生明显的猝灭,猝灭程度可达到92.63%.通过引入乙二氨基团BAEAHQA达到了发光基团与螯合基团之间的分离,有效地避免了pH值对发光的影响.实验结果表明,BAEAHQA/MCM4-1对于金属离子具有良好的传感特性.
The quinacridone derivative 5,12-bis [ 6-(2-amino-ethylamino) -hexyl ] qunacridone (BAEAHQA) which can be used as chelate ligand to coordinate with metal ions, was successfully incorporated into mesoporous molecular sieve MCM-41. The emission spectra indicate that BAEAHQA/MCM-41 emits a great yellowish-green light, which is similar with BAEAHQA in liquid state. And metal ions could quench the luminescence of BAEAHQA/MCM-41, especially when Co^2+ ions exist, the luminescence of BAEAHQA/MCM-41 was quenched completely. It is suggested that BAEAHQA/MCM-41 can be used as the metal ions sensing material.
