Two coronoid hydrocarbons, [3]- and [4]chrysaorene were synthesized from fluorenophane precursors using the fold-in strategy. [3]Chrysaorene is a bowl-shaped fragment of the C240-Ih fullerene, whereas [4]chrysaorene is planar and contains a uniquely large 24-membered internal ring. Chrysaorenes show geometry-dependent magnetic properties and are strongly fluorescent.
