Achiral [2]catenanes composed of rings with inequivalent sides may adopt chiral co-conformations. Their stereochemistry depends on the relative orientation of the interlocked rings and can be controlled by sterics or an external stimulus (e.g., a che

Complex molecular knots and links are still difficult to synthesize and the properties arising from their topology are mostly unknown. Here, we report on a comparative photophysical study carried out on a family of closely related quinolinium‐based

A molecular Solomon link adopts different conformations in acetonitrile (1) and in water (2). Contrary to expectations, the main driving force of the transformation is not the change in medium polarity, but the cooperative binding of about four molec

Conventional approaches to the synthesis of molecular knots and links mostly rely on metal templation. We present here an alternative strategy that uses the hydrophobic effect to drive the formation of complex interlocked structures in water. We desi

A rapid screening method based on traveling-wave ion-mobility spectrometry (TWIMS) combined with tandem mass spectrometry provides insight into the topology of interlocked and knotted molecules, even when they exist in complex mixtures, such as inter

In this article, we use (1)H NMR spectroscopy to study the spontaneous molecular motion of donor-acceptor [2]catenanes in water. Our data supports the hypothesis that conformational motion dominantly occurs through a pirouetting mechanism, which invo

The hydrophobic effect promotes the self-assembly of imine-based [2]catenanes in pure water.
We report the efficient condensation of imine-based macrocycles from dialdehyde A and aliphatic diamines Bn in pure water. Within the libraries, we iden

When it takes eight to tango: Since the synthesis of the simplest of all knots, the trefoil knot, in 1989, the formation of more complex knots has remained extremely challenging. The synthesis of the most complex molecular knot made to date, the 819
