title: Combining coordination chemistry and catalysis to tie a knot by an active-metal template strategy.
abstract: Collar and tie men: the smallest trefoil knot reported to date has been prepared by an active metal template synthesis. Copper(I) ions are able to constrain the well-designed structure so that it can form the loops by complexing to the bipyridine moieties in the core of the thread and the two ends of the entangled lace on opposite faces of the loop, before acting as a catalyst to close the lace.
