Ionization Energy of Fullerenes

Ionization energies of the higher fullerenes C n (n = 70−106) were measured by means of the ion-molecular equilibria−Knudsen cell mass spectrometry method. The obtained values were found to decrease with the size, going from IE(C70) = 7.36 eV down to IE(C106) = 6.92 eV, with unexpectedly low IE(C74)...

Summary:Ionization energies of the higher fullerenes C n (n = 70−106) were measured by means of the ion-molecular equilibria−Knudsen cell mass spectrometry method. The obtained values were found to decrease with the size, going from IE(C70) = 7.36 eV down to IE(C106) = 6.92 eV, with unexpectedly low IE(C74) = 7.13 eV. A good correlation of the experimental results with the theoretical values is demonstrated. A simple model describing the ionization properties dependence from the fullerene size is proposed.
