Highly stable porous polymer networks (PPNs) are synthesized through a Yamamoto homocoupling reaction between tetrahedral monomers. Among those polymers, PPN-4 shows exceptionally high Langmuir surface area of 10063 m(2) g(-1) (SA(BET): 6461 m(2) g(-1)). It also exhibits ultra high hydrogen, methane, and carbon dioxide storage capacities. These properties make it a perfect adsorbent for clean energy applications.
