摘要: 建立了有机物粉末二次谐波(SHG)的测量系统。测定了N-烃基口丫啶酮衍生物粉末的SHG,并以溶剂变色法测定了一些口丫啶酮衍生物的分子超极化率与分子基态偶极矩的复合量(βCTμg).从分子结构特征与分子折射率等方面对其所表现出的非线性光学性质进行了分析。具有“Λ”型多极结构、分子间氢键、支化烷基和甲基的口丫啶酮衍生物,粉末SHG较强;βCTμg与SHG相对强度近似线性关系;分子折射率与SHG不满足Kurtz-Pery关系。

Abstract: A second harmonic generation (SHG) measurement system for organic powders have been built.Then the second order nonlinear optical properties of acridine derivates have been measured with this experimental setup and compared with the calculated value obtained by the solvatochromic method.The intensity of second harmonic generation of acridine derivate microcrystal was related to its structure and molecular refractive index.Acridines with two dimension dipole "Λ" type structure,intermolecular hydrogen bond,long chain alkyl with branches and methyl group possess high nonlinear optical properties.The relative SHG of these microcrystals were proportional to their hypersusceptibilities,but not comformed to the Kurtz Perry relation.
