二茂铁Schiff碱类三阶非线性光学材料的合成

Synthesis of Ferrocenyl Schiff Bases Organometallic Compounds with Third-order Nonlinear Optical Properties

以二茂铁、取代胺为原料,经甲酰化、缩合反应,合成了7个具有大π共轭体系的二茂铁席夫碱有机金属三阶非线性光学材料。优化了2-氨基-6-硝基苯并噻唑与二茂铁甲醛缩合的反应条件,筛选了催化剂、溶剂,得出以碱性A l2O3为催化剂,以二甲苯为溶剂,在回流温度下,反应10 h,产物收率可达59.1%。比较了不同的取代胺对反应收率的影响,得出胺的碱性越强,反应收率越高。经核磁共振氢谱、紫外光谱、质谱等表征了目标化合物的结构。

Seven ferrocenyl Schiff based organometallic compounds with third-order nonlinear optical properties,which had large π-conjugated systems,were designated and synthesized starting from ferrocene and substitutional amine.The process of the condensation of ferrocenecarboxaldehyde and 2-amino-6-nitrobenzothiazole was selected.The results showed that the optimal parameters were as follows：catalyst alkaline Al2O3,solvent xylene,reflux 10 h.The highest yield was 59.1%.The influence of different substituted amine on the reaction yield was compared.It was concluded that the amine with more intense basicity give the higher yield.All the compounds were characterized by 1HNMR,MS and UV.
