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 …

Porphyrins feature prominently in nature, be it as enzymatic cofactors, electron and exciton
shuffles, as photoactive dyes, or as signaling substances. Their involvement in the …

Porphyrins are variously substituted tetrapyrrolic macrocycles, with wide-ranging biological
and chemical applications derived from metal chelation in the core and the 18π aromatic …

This tutorial review summarises different aspects of cooperativity in supramolecular
complexes. We propose a systematic categorisation of cooperativity into cooperative …

Conspectus The ring currents of aromatic and antiaromatic molecules are remarkable
emergent phenomena. A ring current is a quantum-mechanical feature of the whole system …

Conspectus This Account is about templates as construction tools: molecules for making
molecules. A template organizes the reactants and provides information to promote …

Aromaticity can be defined by the ability of a molecule to sustain a ring current when placed
in a magnetic field. Hückel's rule states that molecular rings with [4 n+ 2] π-electrons are …

Molecular knots are often prepared using metal helicates to cross the strands. We found that
coordinatively mismatching oligodentate ligands and metal ions provides a more effective …

Background The size and complexity of molecules being studied by single crystal diffraction
is growing year by year, resulting in an increase in the difficulties encountered during …

Small alterations to the structure of a star‐shaped template totally change its mode of
operation. The hexapyridyl template directs the conversion of a porphyrin dimer to the cyclic …
