摘　　要：以1,4-萘醌为原料,合成了含硫的醌构稠杂环化合物苯并[b]萘并[2′,3′∶5,6][1,4]二噻英并[2,3-i]噻蒽-5,7,9,14,16,18-六酮(4),其结构经1HNMR和IR确证。采用波长为800nm,脉宽为80fs的Ti∶Sapphire飞秒激光,运用双光束简并四波混频法测定了4的三阶非线性光学性能,结果表明,4的三阶非线性光学极化率χ(3),非线性折射率n2,分子二阶超极化率γ和响应时间分别为2.89×10-13esu,5.31×10-12esu,3.14×10-31esu和101fs。并分析了4的分子结构对其三阶非线性光学性能的影响。Benzo[b] naphtho [2＇,3＇：5,6][1,4] dithiino [2,3-i] thianthrene-5,7,9,14,16,18-hexone （4） was synthesized from 1,4-naphthaquinone and the structure was confirmed by ^1H NMR and IR. The third-order optical nonlinearity of 4 was measured by using Ti ： sapphire femtosecond laser （γ = 800 nm, l0 = 80 fs） and two-beam degenerate four-wave mixing technique. The third-order nonlinear optical susceptibility χ^（3）, the nonlinear refractive index n2, the second-order hyperpolarizability γ and response time of 4 were was 2.89×10^-13 esu, 5.31×10^-12 esu, 3.14×10^-31 esu and 101 fs, respectively. The influence of the molecular structure of 4 on the third-order optical nonlinearity was analyzed.
