Abstract:
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 [8]annulene hydrocarbons, best exemplified by its simplest member cyclooctatetraene, are less exploited in functional molecules. From a design perspective this is unfortunate as the [8]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 [8]annulene hydrocarbons and approaches to exploiting their fluxional and responsive topology in catalysis and intrinsically responsive switchable materials will be discussed.
