Contribution

It provides new insights into the NLO behavior of MPF with polysiloxane copolymers, highlighting marginal effects on optical limiting and photoluminescence.

Findings

MPF's optical limiting is poorer than C60.

Polysiloxane attachment shows marginal improvement.

Photoluminescence of MPF-containing polymers is slightly enhanced.

Abstract

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 C60, while the contribution of PSI-46 attached to the MPF shows marginally improvement from the ratio of MPF/PSI-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 behaviour are discussed.
