英文摘要	steric hindrance and hyperconjugative effects, introduced at the n1 position of 2-methylimidazolium, greatly enhance the alkaline stability of the 2-methylimidazolium functional group. 2-methylimidazolium small molecule compounds with n1-substituents (butyl, hexyl or octyl) are stable in 1 m koh at 80 degrees c for more than 3000 h. accordingly, the membranes based on n1-butyl, hexyl or octyl-substituted 2-methylimidzolium exhibited much more alkaline stability than membranes based on other substituted 2-methylimidazolium compounds, reflected by the almost unchanged iec, conductivity and dimensions of the membranes after being exposed to 1 m koh at 60 degrees c for hundreds of hours. this work reports the preparation of highly alkaline stable 2-methylimidazolium-based membranes by modifying the n1 position of 2-methylimidazolium.
