Our recent research efforts on the synthesis of nonplanar nanographenes bearing tribenzotriquinacene or fenestrindane skeleton are summarized. Wizard hat-shaped or saddle-shaped nanographenes could be prepared using a non-classical Scholl-type cycloheptatriene formation or 19-membered ring macrocyclization. The key to the success of these transformation relies on the proper installation of the electron rich aryl functional groups in the bay areas of these molecular motifs. The three-dimensional structures of some of the nanographenes were determined by X-ray crystallography. Furthermore, these carbon-rich π-conjugated molecules are also showed to have interesting photophysical, self-assoication and host-guest complexation properties.

Key words: nonplanar aromatics, nanographenes, tribenzotriquinacene, fenestrindane
