A new fluorescent hybrid porous polymer (HPP) is synthesized by an anhydrous FeCl 3 ‐mediated oxidative coupling reaction of octa[4‐(9‐carbazolyl)phenyl]silsesquioxane (OCPS). The polymer possesses a surface area of 1741 m 2 g −1 and hierarchical bimodal micropores (1.41 and 1.69 nm) and mesopores (2.65 nm). The material serves as an excellent adsorbent for CO 2 and dyes with high adsorption capacity for CO 2 (8.53 wt %,1.94 mmol g −1 ), congo red (1715 mg g −1 ) and rhodamine B (1501 mg g −1 ). In addition, the presence of peripheral cabozolyl groups with extended π‐conjugation in the crosslinked framework imparts luminescent character to the polymer and offers the detection of nitroaromatic compounds.
