通过后合成修饰将水杨醛(Salicylaldehyde,sal)锚装在金属-有机框架化合物IRMOF-3(Isoreticular metal-organic framework-3) 上得到IRMOF-3-sal,采用不同乙酰丙酮盐对其进行配位共价修饰。研究了所得化合物IRMOF-3-Msal的固态荧光峰位及强度变化,结果显示IRMOF-3-Msal峰位均发生了不同程度的蓝移,其中IRMOF-3-Znsal的蓝移最大且荧光强度显著增强。另外,对比了金属乙酰丙酮盐与硝酸盐修饰后的IRMOF-3-sal的固态荧光光谱,从而为金属-有机框架化合物的配位共价修饰提供了有力的实验依据。
An isoreticular metal-organic framework(IRMOF-3) was modified with salicylaldehyde(sal) by postsynthetic modification(PSM) method.The compound was metallated with M(acac)n(M=Mg,Zn,Pr,Ni) and the characteristics of the complex of IRMOF-3-Msal were investigated by solid-state fluorescence spectroscopy.The emission peaks of IRMOF-3-Znsal exhibited the maximum blue shifted behavior and stronger relative fluorescence intensity.The further research indicated the fluorescence variations of IRMOF-3-sal metallated with M(NO3)n were better than that with M(acac)n.
