Corannulene(CAT: R025288) is a bowl-shaped polycyclic aromatic hydrocarbon (PAH) consisting of a curved π-conjugated carbon framework. Often described as a fragment of fullerene (buckyball) structures, it serves as a key model compound for studying carbon curvature, aromaticity, and electron delocalization. Its unique geometry makes Corannulene highly valuable in nanotechnology, supramolecular chemistry, and materials science, where it supports the design of organic semiconductors, molecular electronics, and carbon-based nanostructures. In addition, Corannulene’s reactivity and ability to undergo functionalization provide opportunities for building advanced materials and exploring host–guest interactions.
