■Abstract
With the rapid development of economic integration and regional conservation worldwide, the growth of green and sustainable resources has attracted great attention. Polymer electrolyte fuel cell (PEFC) is a model of green, resource-saving, and environmental protection energy. We synthesized various porous organic polymers (POPs) via simple and cost-effective methods, which are applicable to most aromatic framework. Sulfonated POPs with high-density sulfonic acid groups were prepared through post-sulfonation. The obtained electrolytes exhibited excellent proton conductivity of 10-2 to 10-1 S cm-1. Results of this study indicate that the structure of sulfonated POPs offers a simple and universal synthetic method for evolving structural design for highly proton-conductive materials.

■Comment
It is a great honor for us to be selected as the Hot Article at Materials Chemistry Frontiers. I would like to gratitude to Prof. Yuki Nagao, Dr. He Li, and all our lab members for contributions and support to this work. I also appreciate the support by JSPS. We believe that this research is a step towards achieving our research goals and inspiring us to do better in the future.
