摘要：

通过Wittig反应和Vilsmeier反应合成了一种以双呋喃为共轭桥, 2,2,3-三甲基-4-氰基-5-二氰基亚甲基-2,5-二氢呋喃(TCF)为受体, 并以二甲胺基为给体的有机非线性生色团分子MF3C, 利用红外光谱、 1H NMR和元素分析对其结构进行了表征. 热重分析结果表明, 该分子的热分解温度达228℃; 利用溶致变色法对该生色团分子的二阶非线性品质参数μgβ进行了计算, 在1064 nm波长下MF3C的μgβ值达到5.9×10-44 esu. 可见, 该生色团兼具较好的热稳定性和较大的超极化率.

Abstract:

It has been demonstrated that organic second-order nonlinear chromophore, with hetero-aromatic ring as the conjugating bridge, has large hyperpolarizability. In this work, with the aim of studying the hyperpolarizability influenced by the length of conjugating bridge, a novel organic non-linear optics(NLO) chromophore MF3C containing bifuran conjugating bridge, tricyanofuran as electron acceptor and dimethylamine as donor was synthesized through Wittig reactions and Vilsmeier reactions. The new chromophore was characte-rized by FTIR, 1H NMR and elemental analysis. Thermogravimetric analysis(TGA) test revealed that the decomposition temperature(Td) of the molecular was up to 228℃. Solvatochloroform method was used to calculate the hyperpolarizability(μgβ). We got the μgβ value of MF3C led to 5.9×10-44 esu at 1064 nm. With good thermal stability and large hyperpolarizability simultaneously, the chromophore shows great potential applications in electro-optic devices.
