摘　　要：合成了一种新型的具有光活性和氧化还原活性的两亲性分子——4-(11-二茂铁基正十一烷氧基)偶氮苯甲酸(FcAzCOOH),采用元素分析、核磁共振氢谱和傅里叶变换红外光谱对产物进行了确认与表征.紫外-可见吸收光谱研究表明,FcAzCOOH在四氢呋喃溶液中具有很好的光致异构行为.循环伏安行为研究表明,FcAzCOOH在N,N-二甲基甲酰胺溶液中的电极过程为受扩散控制的可逆过程,紫外光照对FcAzCOOH的电化学行为几乎没有影响.A novel amphiphilic ferroceneylazobenzoic acid （FcAzCOOH） with optical and redox activities was synthesized, and the product was identified and characterized by means of elemental analysis, 1H NMR and FT-IR. Then, the photochemical behavior of FcAzCOOH in tetrahydrofuran solution was invenstigated by means of UV-Vis, with an excellent photoisomerization behavior being discovered. Moreover, the electrochemical behavior of FcAz- COOH in polar DMF solution was analyzed by means of cyclic voltarnmetry. The results show that the electrochemical response of FcAzCOOH is dispersion-controlled and reversible, and that UV light has no obvious effect on the electrochemical behavior of FcAzCOOH.
