Abstract

Buckybowls attract significant attention in chemistry and materials science owing to their unique features related to both geometric and electronic aspects. Doping the π-skeleton of buckybowls with the main group elements results in hetera-buckybowls, and accordingly has a large influence on the chemical and physical properties. This account summarizes our research progress on hetera-buckybowl trichalcogenasumanenes (TCSs), including their synthesis, regioselective oxidations, transformation into various hetero polycycles (chiral π-systems, molecular spoons, etc.), and their application as optoelectronic materials.
