Tuning the Interlocking in Partially Saturated Copper(I) Rotaxane Complexes for O2-to-H2O Electrocatalytic Reduction

Abstract

We developed tridentate rotaxane ligands to stabilise a dynamic Cu(I) centre with an empty coordination site for O2 reduction. Electrocatalytic activity and selectivity can be controlled by the interlocking tightness through varying the macrocycle size, a feat traditionally inaccessible by non-interlocked analogues.
