Outline of Final Research Achievements

In this work, we developed a novel synthetic methodology, ‘Annulative π-Extension (APEX)’, for the efficient synthesis of π-extended polycyclic aromatic hydrocarbons (PAHs), nanographenes, and π-extended heteroaromatics, which gather immense intrest in the field of synthetic chemistry and materials science. Newly developed palladium-catalyzed APEX systems enabled the one-step synthesis of those π-extended aromatics by directly using unfunctionalized PAHs and heteroaromatics. Sequential annulative π-extension, so-called APEX polymerization, was also possible to provide structurally uniform graphene nanoribbons in a single operation.
