摘　　要：Four fullerene dyads with different cabazole units,named a,b,c,d,were studied by using a femtosecond laser with 780 nm wavelength using Z-scan methods.Interestingly,all of them show strong two-photon induced excited-state absorption behaviors,which were observed firstly in femtosecond timescale.The values of their excited-state absorption cross-section were up to 6.07×10^(-18),7.27×10^(-18),3.86×10^(-18) and 4.51×10^(-18) cm^(-1) for a,b,c,and d,respectively.
