采用后合成修饰技术将水杨醛锚装在金属-有机骨架化合物UMCM-1-NH2上,得到一种席夫碱功能化的多孔化合物UMCM-1-Sal,利用其孔道内的N, O原子易与金属离子配位的特点,捕获了一系列金属离子[ Mg(Ⅱ), Zn(Ⅱ), Co(Ⅱ), Ni(Ⅱ), Cd(Ⅱ), Fe(Ⅲ), Cu(Ⅱ)],并对比研究了它们的光致发光行为。结果表明,与UMCM-1-NH2相比, UMCM-1-Sal的荧光发射峰红移,荧光强度降低,捕获金属离子后其荧光强度又有所增强,其中捕获镁后的荧光增强最明显。

Salicylaldehyde( Sal) was anchored on the pore of UMCM-1-NH2 by postsynthetic modification of metal-organic frameworks(MOFs) to yield a functionalized MOF with Schiff base group(UMCM-1-Sal). The capturing capacities of UMCM-1-Sal for different metal ions( Mg, Zn, Co, Ni, Cd, Fe, Cu) were investigated by solid state fluorescence spectra which indicated that the luminescence of the compounds after capturing some metal ions were enhanced, and exhibited a high Mg2+-specific luminescence enhancement. The results would be helpful for the design and preparation of new fluorescent probes for Magnesium ion.
