Popis:	The nonlinear optical (NLO) response of some water soluble C 70 dendrimers was studied under nanosecond and picosecond laser excitation in the visible (at 532 nm) and is compared with the response of pristine C 70 dissolved in toluene. The NLO response of the dendrimers was found to be about seven times smaller than that of C 70 under ns excitation, while no response was found under ps excitation. The second hyperpolarizability γ of both the C 70 dendrimers and pristine C 70 were determined and compared with other published results.
