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5.9×10-44esu.可见,该生色团兼具较好的热稳定性和较大的超极化率.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.
