title: Quadruple anionic buckybowls by solid-state chemistry of corannulene and cesium.
abstract: The buckybowl corannulene is known to be an excellent electron acceptor. UV photoelectron spectroscopy studies were performed with thin-film systems containing corannulene and cesium. Adsorption of submonolayer quantities of corannulene in ultrahigh vacuum onto thick Cs films, deposited at 100 K on a copper(111) substrate, induces a transfer of four electrons per molecule into the two lowest unoccupied orbitals. Annealing of thick corannulene layers on top of the cesium film leads to the formation of a stable film composed of C20H10(4-) ions coordinated to four Cs(+) ions. First-principles calculations reveal, as the most stable configuration, four Cs(+) ions sandwiched between two corannulene bowls.
