Purpose of this study was as follows :A. To control orientation of complex cations in a crystal by controlling the symmetry of the complex cations.B. To study the electro-optic effect of the crystals.Here is a summary of main results.1 Precise measurement of the electro-optic effectIn order to estimate the electro-optic effect precisely, a transmission method and a reflection method were investigated using single-crystal samples, and the reflection method was proved to have some advantages in the electro-optic measurement.2 Crystallization in two different crystal systemsA chiral dinuclear nickel(II) complex was shown to crystallize into two different crystal systems under different conditions ; One was polar and the other was not polar.3 Search for new promising compoundsSome new transition metal complexes were prepared using chiral ligands.4 Observation of the fourth-order electro-optic effectElectro-optic effect of some compounds were measured. Especially, a D_2 symmetric crystal showed a fouth-order electro-optict effect ; a change in refractive index was proportional to the fourth power of the external electric field.

这项研究的目的如下：通过控制复合阳离子的对称性来控制晶体中复杂阳离子的取向。在这里是主要结果的摘要。在不同条件下，镍（II）配合物被证明可以结晶成两个不同的晶体系统。 3搜索使用手性配体制备了新的有前途的化合物新的过渡金属配合物。4观察某些化合物的四阶电效应效应效应。尤其是，D_2对称晶体显示出fouth阶的电击效应。折射率的变化与外部电场的第四次功率成正比。
