[2]Catenane, [2]rotaxane, and [2]pseudorotaxane based on a cyclic titanium oxide cluster, [Ti8O8(SO4)16]16– (Ti8), and cyclic/linear alkylammonium cations are reported. Their syntheses, structures, spectroscopy, and stability in water were studied. These molecules were synthesized from and remained intact upon redissolution in acidic water. Hence, the cluster Ti8 is a promising metal oxide ring that
报道了基于环状氧化钛簇的 [2] 链烷、[2] 轮烷和 [2] 假轮烷、[Ti 8 O 8 (SO 4 ) 16 ] 16– ( Ti 8 ) 和环状/线性烷基铵阳离子。研究了它们的合成、结构、光谱和在水中的稳定性。这些分子从酸性水中合成并在重新溶解在酸性水中时保持完整。因此,团簇Ti 8是一种很有前途的金属氧化物环,可用作冠醚的无机类似物,在水中组装无机-有机杂化机械互锁超分子组装体。
