The simplest design element in a molecule is perhaps shape. Because it is such a fundamental concept, specific molecular shapes tend to find many and diverse uses. The flat benzene ring serves as an illustration; it is found from 2D-materials like graphene, to drugs, ligands in metal catalysis, and more. In comparison, the structurally related all-sp2 annulene hydrocarbons, best exemplified by its simplest member cyclooctatetraene, are less exploited in functional molecules. From a design perspective this is unfortunate as the annulene core pairs a distinct and rather unique tub-shape with an intrinsic topological response to redox changes suggesting a plentitude of still untapped applications.
Or work on the synthesis of annulene hydrocarbons and approaches to exploiting their fluxional and responsive topology in catalysis and intrinsically responsive switchable materials will be discussed.
