    An electrically driven motor on the molecular scale based on [3]catenane is described, in which two cyclobis(paraquat-p-phenylene) rings operate by means of redox reactions, demonstrating highly unidirectional movement around a circular loop.

    A molecular ratchet, in which a crown ether is pumped from solution onto an encoded molecular strand by a pulse of chemical fuel, opens the way for the reading of information along molecular tapes.

    A molecular-scale pump whose operation is driven by a catalytic process when in the presence of chemical fuel is autonomous, within an operating window, as long as the fuel lasts.

    A molecular strand can be knotted and unknotted into three different topologies, depending on the complexing metal ion used (copper or lanthanide or none).

    A system is described in which a small macrocycle is continuously transported directionally around a cyclic molecular track when powered by irreversible reactions of a chemical fuel; such autonomous chemically fuelled molecular motors should find application as engines in molecular nanotechnology.
