摘要
目的合成一种新型含联吡啶单元的共价有机框架(COF)材料并对所制COF材料的结构及性能进行了分析表征。方法以2,2'-联吡啶-5,5'-二甲醛和2,4,6-三(4-氨基苯基)-1,3,5-三嗪为原料,通过席夫碱反应合成了一种新型含联吡啶单元的共价有机框架(COF)材料。结果COF材料的丙酮分散液中加入各种金属离子盐溶液,发现加入Fe^(3+)时COF材料分散液的荧光强度明显降低,而加入其他金属离子时的荧光强度变化不大。结论COF材料在有机溶剂中具有良好的稳定性并且是一种潜在的Fe^(3+)荧光探针。
Purposes—To synthesize a new type of covalent organic framework(COF)material containing bipyridine units and analyze and characterize the structure and properties of the prepared COF material.Methods—A novel covalent organic framework material containing bipyridine unit was synthesized by a schiff base reaction with 2,2'-bipyridyl-5,5'-dialdehyde and 2,4,6-tris(4-aminophenyl)-1,3,5-triazine as raw material.Result—When adding various metal salt solutions into the acetone dispersion solution of the COF,it was found that the fluorescence intensity of the dispersion solution changed most obviously when Fe^(3+) was added.However,the fluorescence intensity changed little when other metal ions were added.Conclusion—This COF has a good chemical stability in common organic solvents and is a potential Fe^(3+) fluorescence probe.
