Entangling strands in a well-ordered manner can produce useful effects, from shoelaces and
fishing nets to brown paper packages tied up with strings. At the nanoscale, non-crystalline …

Molecular nanotopology—a term we coined recently—is a rapidly develo** field of
research that is emerging out of the confluence of chemical topology with the mechanical …

Current strategies for the synthesis of molecular knots focus on twisting, folding and/or
threading molecular building blocks. Here we report that Zn (ii) or Fe (ii) ions can be used to …

Mechanically interlocked molecules (MIMs), such as rotaxanes, catenanes, and molecular
knots, have attracted significant interest because of their unique properties originating from …

The simultaneous synthesis of a molecular nine-crossing composite knot that contains three
trefoil tangles of the same handedness and a 9 7 3 link (a type of cyclic [3] catenane …

From being an aesthetic molecular object to a building block for the construction of
molecular machines, catenanes and related mechanically interlocked molecules (MIMs) …

Molecular knots attract attention on account of their topological intricacies and potential
application. Tying molecular knots with different topologies, on larger length scales, remains …

By utilizing an underexplored reactivity mode of N-aminopyridinium ylides, we developed
the visible-light-induced ortho-selective aminopyridylation of alkenes via radical-mediated 1 …

A (FeII) 6-coordinated triply interlocked (“Star of David”)[2] catenane (612 link) and a (FeII) 5-
coordinated pentafoil (51) knot are found to selectively transport anions across phospholipid …

We report on the stereoselective synthesis of trefoil knots of single topological handedness
in up to 90% yield (over two steps) through the formation of trimeric circular helicates from …
