Abstract:Bowl-shaped π-conjugated compounds including partial structures of the fullerenes or cap structures of carbon nanotubes, which are called "buckybowls", are of importance not only as model compounds of fullerenes but also as their own chemical and physical properties. For example, in solution they show the characteristic dynamic behavior such as bowl-to-bowl inversion. In contrast, they sometimes favor stacking structure in a concave-convex fashion in the solid state, giving excellent electron conductivity. Some buckybowls are conceivable to possess the bowl-chirality if the racemization process, as equal as bowl-to-bowl inversion, is slow enough to be isolated. In this lecture, I demonstrate the first synthesis ofC_3vsymmetric buckybowl, sumanene [1-3] and recent progress toward the general and facile synthetic method to constructC₃symmetric buckybowls including asymmetric synthesis [4] of nitrogen-doped heterabuckybowls [5].
