Controlling the mobile ion content of ion-containing polymers is critical for advanced organic electronic applications. Here, we report a chemical strategy for achieving “on-demand” release of ions in polymeric materials by incorporating thermally labile Diels–Alder linkages into polymerized ionic liquids. Electrical characterization demonstrates a clear increase in mobile ion content at the retro-Diels–Alder temperature, which is retained after the material is returned to room temperature. This work demonstrates that chemical triggers can be utilized to release ions and change the mobile ion content of a polymeric material after the sample is prepared, paving the way for new classes of responsive organic electronic devices.

包含热不稳定Diels-Alder键的聚合离子液体中的可触发离子释放

控制含离子聚合物的移动离子含量对于先进的有机电子应用至关重要。在这里，我们报告了一种化学策略，该方法通过将热不稳定的Diels-Alder键结合到聚合的离子液体中来实现聚合物材料中离子的“按需”释放。电气特性表明，在逆Diels-Alder温度下，移动离子含量明显增加，在材料恢复到室温后，这种趋势得以保留。这项工作表明，在制备样品后，可以利用化学触发来释放离子并改变聚合物材料中的可移动离子含量，从而为新型响应有机电子设备铺平了道路。
