Abstract Pillar[5]quinone (PQ[5])‐based porous polymer has been prepared by crosslinking and oxidating pillar[5]arene (PA[5]). Quinone was used as an unorthodox ligand to load palladium‐catalyst with high loading ratio (up to 12.0 wt %). Catalyst was well dispersed on solid support in the form of Pd 2+ ‐specie. Pd‐loaded PQ[5]‐based heterogeneous catalyst was highly efficient for Suzuki‐coupling reactions (22‐ to 1485‐fold higher than Pd/C based on turnover frequency). It was superior compared to other existing heterogeneous catalysts for selective catalytic reaction. This heterogeneous catalyst had good thermo‐stability, and could be reused and recycled.
