摘要： 合成并表征了一种新的非两亲性共轭桥联双二茂铁衍生物,该化合物在空气/水界面上易形成较稳定的单分子膜,与花生酸形成的混合膜易组装成LB膜,紫外-可见吸收光谱表明:LB上膜分子中发生了聚集,扫描电镜观察了混合单层LB膜的表面形貌及膜的相分离。循环伏安研究表明:混合单层LB膜修饰电极对Fe(CN)63-/Fe64-离子对的电化学反应具有良好的电催化效应,对抗坏血酸电化学氧化具有明显的促进作用。

Abstract: A new non-amphiphilic biferrocene connected by a conjugated bridge group is synthesized and characterized. The biferrocene is able to form a relatively stable monolayer.As it is mixed with arachidic acid, the mixed monolayer is easily assembled to LB film.The UV-Vis spectra show that the aggregate is formed in the molecules on monolayer.By means of scanning electron microscope, the morphological structure of biferrocene and arachidic acid on LBfilm has been observed, and phase separation in the mixed film can be monitored.The electrochemical reaction of Fe(CN)63-/Fe64-(CN)solution is electrocatalyzed by the mixed LB film on ITO electrode. and electrochemical oxidation reaction.of ascorbic acid can be improved by the mixed film.
