副族金属卤化物与POM的配合物的二次谐波效应与晶体结构的关系

Relationship Between SHG Effect and Crystal Structure in Complexes of Sub-Group Metal Halide and POM

已发现某些金属有机配合物是一类有前景的非线性光学材料，为了系统地探索二次谐波发生（ＳＨＧ）效应大、综合性能好的新型金属有机配合物非线性光学晶体材料，则有必要探讨它们的性能与结构之间的关系。考虑到某些具有较大二阶极化率的有机分子可能与副族金属卤化物形成配合物，于是对这些配合物的二次谐波效应与晶体结构的关系进行了较系统的研究，发现它们实测的ＳＨＧ强度的大小与晶体的配位键中离子键和共价键成分的大小相一致。

Some organometallic complexes which are a type of potential nonlinear optical materials have been discovered.In order to make a systematic exploration for new organometallic complexes exhibiting large second harmonic generation(SHG)effect and good comprehensive properties ,it is necessary to study the relationship between the property and the structure. Considering the possibility of forming complexes between some organic molecular crystals exhibiting good SHG effect and metallic ions of the sub-group,the relationship between the second-harmonic effect and the crystal struture of these complexes was investigated systematically.The experimentation discovered that the regularity of their SHG intensity agree with the regularity of the crystal structure.
