通过二硼化离子液体在双功能配体存在下的自组装反应，制备了新型超分子型固体聚合物电解质。所得聚合物在甲醇中具有良好的溶解性，其结构得到H-1和B-11 NMR谱的支持。样品彻底干燥后，采用交流阻抗法评价聚合物的离子电导率。在51 ℃下，在等摩尔量的LiTFSA与离子液体单元的存在下，观察到的离子电导率为8.8 × 10（-6）至5.4 × 10（-6）S cm（-1）。离子电导率的温度依赖性被成功地拟合到VFT（Vogel-Fulcher-Tamman）图，表明离子传导是根据粘性基质中典型的离子输运模型发生的。(C)2009爱思唯尔有限公司版权所有。
Novel supramolecular type solid polymer electrolytes were prepared by self-assembly of diborylated ionic liquid in the presence of bifunctional ligands. The polymers obtained were well soluble in methanol, and their structures were supported by H-1 and B-11 NMR spectra. The ionic conductivity of the polymers was evaluated by ac-impedance method after the samples were dried thoroughly. The ionic conductivity observed was 8.8 x 10(-6) to 5.4 x 10(-6) S cm(-1) at 51 degrees C in the presence of equimolar amount of LiTFSA to ionic liquid unit. The temperature dependence of ionic conductivity was successfully fitted to VFT (Vogel-Fulcher-Tamman) plots, indicating that ionic conduction is taking place according to typical ion transport model in viscous matrix.
