An iridium pincer complex {p‐KO‐C6H2‐2,6‐[OP(t‐Bu)2]2}Ir(C2H4) is immobilized in a propyl bromide‐functionalized microporous polymer network using the concepts of surface organometallic chemistry. The support material enables the formation of isolated active metal sites embedded in a chemically robust and highly hydrophobic environment. The catalyst maintained high porosity and – without prior activation – exhibited high activity in the continuous‐flow dehydrogenation of cyclohexane at elevated temperatures. The catalyst shows a stable performance for at least 7 days, even when additional H2O was co‐fed, owing to its hydrophobic nature.
