Three-component nanorotors generated from fusion of complexes and post-fusion metal–metal exchange

Abstract

The fusion of two homoleptic complexes quantitatively created a novel three-component nanorotor. The intra-supramolecular rotational dynamics leads to a rapid exchange (k₂₉₈ = 24.0 ± 2.5 kHz) of two degenerate N_py → ZnPor interactions. Metal exchange at the remote HETTAP complexation site provided a faster nanorotor (k₂₉₈ = 34.0 ± 3.0 kHz).
