Fullerene molecules due to their three-dimensional delocalization. The electron structure shows a higher third-order nonlinearity (for q: X (’) ~ 10- "XSS) .Lascola reported that the third-order nonlinear polarizability of ions is higher than that of neutral C .. molecules 65 times. The C .. molecules and other non-linear materials (such as polymer materials) to form a charge-transfer material, which can be
