制备了甲苯胺蓝（TBO）功能化的有序介孔碳（OMC）/离子液体（IL）凝胶（gel）纳米复合物.将TBO-OMC/ILgel修饰玻碳（GC）电极，然后进行电聚合，制备聚TBO（PTBO）-OMC/ILgel/GC电极.扫描电镜表征显示PTBO-OMC/ILgel复合物表面形貌均一、规则.最后探讨了pH值在4.0-9.0范围内，对PTBO-OMC/ILgel/GC电极电化学性质的影响.实验结果表明，随着溶液pH值的增大，PTBO的氧化峰和还原峰的峰电位均向负的方向移动.当pH<7.0时，每改变1个pH值，E1/2改变76mV.然而当pH>7.0时，每改变1个pH值，E1/2改变39mV.这是由于PTBO在酸性溶液中的电化学反应为有两个质子参与的过程，而在碱性溶液中为只有一个质子参与的过程.

The composite of toluidine blue O (TBO) functionalized ordered mesoporous carbon (OMC) is prepared by aπ-πstacking interaction. Then the gel is developed based on the polymerization of TBO-OMC and ionic liquid (IL). The polymerization of the TBO (PTBO)-OMC/IL gel is used to modify glass carbon (GC) electrode. The PTBO-OMC/IL gel composite film distributes almost homogeneously with unique structure on the surface of substrate characterized with the scanning electron microscopy. At last, the effect of pH is investigated at the PTBO-OMC/IL gel/GC electrode in the pH range from 4.0 to 9.0. The study shows that anodic and cathodic peak potential for the redox couple of PTBO are pH dependent and they shift toward a negative direction with increasing solution pH. The slope is 76 mV per pH unit when pH<7.0. However, these values change to 39 mV per pH unit when pH>7.0. The electrode reaction of PTBO companies with a two-proton transfer with variable values of pH in acidic solution, while one-proton in the alkaline.
