Synthesis of diaza-bridged C60 and its nonlinear optical properties

The nonlinear optical property and optical limiting property of a new diaza-bridged C60 derivative were studied by means of z-scan technique and experiment under irradiation of 8ns pulse duration at 532nm. The reverse saturation absorption and nonlinear refraction were observed by means of z-scan technique . The nonlinear absorption coefficient and the value of the third-order nonlinear optical susceptibilities (3) were obtained respectively. The compound had lower value of the optical limiting clamp. All the results show that this compound has a good optical limiting performance.
