Abstract Anionic microporous polymer networks were synthesised via Yamamoto polymerization of a fluorinated tetraarylborate monomer. The network charge density can be controlled by varying the incorporation ratio of a neutral tetraphenylmethane comonomer. The resulting polymer networks demonstrated exceptional stability under ambient conditions and achieved specific surface areas of up to 1500 m 2 g −1 . The anionic nature of the networks simplifies postsynthetic ion exchange, enabling the incorporation of catalytically active cationic species. As a proof of concept, the molecular cationic Crabtree's catalyst was immobilised within the network, yielding a solid‐state material that efficiently catalyzed the gas‐phase hydrogenation of ethylene to ethane under mild conditions.
