[2] and [3] hybrid rotaxanes are reported based on {Ti₇M} rings (M is a trivalent metal such as Fe^III or Ga^III). NMR studies show that [2]rotaxanes can act as molecular shuttles, while EPR studies of [3]rotaxanes show weak interactions between the paramagnetic components of the supramolecular assemblies.

杂化有机-无机轮烷，包括具有两个不同的杂金属环和分子梭的杂-杂[3]轮烷

[2]和[3]杂合轮烷据报道基于{Ti ₇ M}环（M为三价金属，如Fe ^III或Ga ^III）。NMR研究表明[2]轮烷可以充当分子穿梭，而[3]轮烷的EPR研究表明，超分子组装体的顺磁性成分之间的相互作用较弱。
