Nonlinear optical performances of supramolecular 1-(4-Methyl)-piperazinylfullerene[60]-containing polysiloxane

Summary form only given. The nonlinear optical (NLO) properties of 1-(4-Methyl)-piperazinylfullerene[60] (MPF) incorporated with a polysiloxane copolymer denoted as PSI-46 have been studied using nanosecond laser pulses at 532-nm -wavelength. The optical limiting performance of MPF itself is poorer than that of its parent C/sub 60/, while the contribution of PSI-46 attached to the MPF shows marginally improvement from the ratio of MPF/PS1-46(1:2) to MPF/PSI-46(1:6). However, the effect can be neglected to the MPF optical limiting responses. The photoluminescence emission of MPF-containing polymers was slightly improved in comparison with that of MPF. The possible sources for the slightly improvement in the NLO behavior are discussed.
