Coordination complexes in which rotaxanes act as ligands for transition-metal atoms are amongst the most celebrated examples of mechanically interlocked molecular level architectures.[1] This is not only because coordination chemistry makes possible a rich diversity of structures, but also because the metal atom can be locked in unusual environments for subsequent electrochemical,[2] photochemical [3] and catalysis [4] ...
