Abstract
The ultrafast nonlinear optical response of C-60-polystyrene n-arm (n = 3,6 ) star polymers in toluene solution is studied using the optical Kerr effec t technique under excitation with 800 nm, 100 fs laser pulses. Their respon se is found to depend on the number and the molecular weight of the arms an d to be much larger than that of pure C-60. Finally, the second hyperpolari zability of the C-60-polystyrene n-arm star polymers is determined. (C) 200 1 Published by Elsevier Science B.V.
