采用简并四波混频方法对平面型络合物阳离子和平面型络合物阴离子所成盐的溶液的三阶光学非线性在1．06μm波长处进行了研究，发现该化合物在纳秒尺度具有较大的非线性响应，而且具有相同的阳离子，而阴离子中金属离子的原子序数较大的样品具有相对较大的三阶非线性极化率。 The third-order optical nonlinearity of the solution formed by the degenerate four-wave mixing method for the salt of the planar complex cation and the planar complex anion was investigated at a wavelength of 1.06 μm and found to be stable at the nanosecond scale Has a larger non-linear response and has the same cation, whereas the sample with larger atomic number of the metal ion in the anion has a relatively large third-order nonlinear polarizability.
