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 …

The discovery of graphene one decade ago has triggered enormous interest in developing
two-dimensional materials (2DMs)—that is 2D allotropes of various elements or compounds …

The binding of multiple guests by a single entity can lead to new modes of host–guest
interactions and thus new applications in, for example, catalysis and sensing. With the aim of …

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 …

With the serendipitous discovery of crown ethers by Pedersen more than half a century ago
and the subsequent introduction of host–guest chemistry and supramolecular chemistry by …

Porosity is a rare property for molecular materials but, surprisingly, porous solids built from
discrete organic cage molecules have emerged as a versatile functional-materials platform …

Two-dimensionally extended, polycyclic heteroaromatic molecules (heterocyclic
nanographenes) are a highly versatile class of organic materials, applicable as functional …

This review summarizes recent advances in the chemistry of curved aromatic molecules. By
focusing on the key accomplishments of the last decade, we provide a general overview of …

This review focuses on the postfunctionalization of porphyrins and related compounds
through catalytic and stoichiometric organometallic methodologies. The employment of …

Porphyrins and other tetrapyrrole macrocycles possess an impressive variety of functional
properties that have been exploited in natural and artificial systems. Different metal centres …
