萘醌并噻唑与二苯并噻蒽系有机三阶非线性光学材料的合成

Synthesis of oganical third-order nonlinear optical materials of dioxonaphthothiazole and dibenzothianthrene compounds

由 1 ,4 萘醌经氯化、氨解、巯基化和缩合环化合成了 5个萘醌并噻唑和四氧二苯并噻蒽系化合物。反应总收率达 45 %～ 85 %。经三维简并四波混频 (3DDFWM)实验测试与计算 ,样品溶液的近红外非共振三阶非线性极化率 χ(3) 达 3 .85～ 4.1 1× 1 0 - 1

Five novel derivatives of dioxonaphthothiazole and tetraoxodibenzothianthrene were synthesized by chlorination、ammonolysis、 mercapto substitution and condensation of 1,4\|naphthoquinone. The yields were 45%～85% respectively. The third\|order nonlinear optical susceptibilities χ\+\{(3)\} of the materials in solution were measured to be 3.85～4.11×10\+\{-13\} esu by three\|dimensional degenerate four \|wave mixing geometry(3D DFWM).
