首次通过简单控制溶剂用量或/和反应温度/时间，成功地合成了三种新型金属-有机骨架(MOF)异构体，它们的孔道大小依次为无孔、微孔和中孔。引人注目的是，我们已经证明了微孔和介孔MOF之间的可逆转变是由溶剂或/和温度扰动引发的。脱溶的微孔分子筛被认为是一种很有前途的小分子荧光探针，而介孔分子筛可以作为大分子染料分子尺寸排斥分离的高效液相固定相。
For the first time, three novel metal-organic framework (MOF) isomers with hierachical channel sizes of nonpore or micropore or mesopore were successfully prepared by simply controlling the amounts of solvent or/and reaction temperatures/time. Strikingly, we have demonstrated the reversible transformation between the microporous and mesoporous MOFs triggered by solvent or/and temperature perturbation. The desolvated microporous MOF has been evaluated to be a promising luminescent probe for detecting small molecules, and the mesoporous MOF could be the stationary phase in high-performance liquid chromatography (HPLC) for size-exclusion separation of large dye molecules.
