摘要
金属有机三阶非线性光学材料是功能材料研究的热点.以二茂铁,2,3-二氯-1,4-萘醌,四氯苯醌,苯甲醛,对苯二甲醛等为原料,分子设计并合成了五个具有大π共轭体系,含二茂铁电子供体,苯醌、萘醌等电子受体的金属有机三阶非线性光学材料化合物,分析合成反应过程并优化了条件,合成化合物Ⅰ和Ⅱ过程中使用二氯甲烷代替甲醇可显著提高收率,在进行Wittig反应时钠氢要明显优于叔丁醇钾.所有化合物均由核磁共振、红外和紫外等表征了结构,收率为41%~83%,方法简单、可行.
In the field of the organic functional materials, organometallic third-order nonlinear optical materials have attracted significant interests. Five Organometallic Compounds with thirdorder nonlinear optical properties were designed and synthesized starting from ferrocene, 1,4- naphthalenedione, 2,3,5,6-tetrachloro-1,4-benzoquinone, benzaldehyde and terephthalaldehyde. These compounds have large π-conjugated systems and contain ferrocene as an electronic donor, benzoquinone or naphthalenediene as an electronic acceptor. The processes of reactions were discussed and the conditions of the reactions were selected. The use of dichloromethane instead of methane can greatly enhance the yield of compound Ⅰ and Ⅱ. Nail is much better than t-BuOK in Wittig reaction. All the compounds were characterized by 1^H NMR, IR and UV. The yields were 41%-83 %. The synthetic methods were simple and feasible.
