supramolecular metal–organic framework wSMOF‐1 has been achieved from intertwined [Ru(tpy)2]2+ (tpy=2,2′,6′,2′′‐terpyridine) complex M1 and cucurbit[8]uril (CB[8]) in water, where the intermolecular dimers formed by the appended aromatic arms of M1 are encapsulated in CB[8]. wSMOF‐1 exhibits ordered pore periodicity in both water and the solid state, as confirmed by a combination of 1H NMR spectroscopy, UV‐vis
交织的[Ru(tpy)2 ] 2+(tpy = 2,2',6',2''-terpyridine)络合物M1和WSMOF-1构成了类金刚石编织的超分子金属有机框架wSMOF-1的自组装。水中的葫芦[8]尿素(CB [8]),其中由M1的附加芳香族臂形成的分子间二聚体被封装在CB [8]中。wSMOF-1在水和固态中均表现出有序的孔隙周期性,这由以下1的组合所证实H NMR光谱,紫外可见吸收,等温滴定量热法,动态光散射,小角X射线散射和选定区域电子衍射实验。机织骨架的孔径为2.1 nm,可自由接触仲,伯醇和叔丁基氢过氧化物(TBHP)。与对照相比,分子的[Ru(TPY)2 ]氯2,所述的[Ru(TPY)2 ] 2+的单元wSMOF-1表现出对醇的氧化通过TBHP显着更高的非均相催化活性Ñ正己烷。对于1-苯基乙-1-醇的氧化,苯乙酮的产率从10%增加到95%。
