Abstract

A new fluorescent hybrid porous polymer (HPP) is synthesized by an anhydrous FeCl₃ -mediated oxidative coupling reaction of octa[4-(9-carbazolyl)phenyl]silsesquioxane (OCPS). The polymer possesses a surface area of 1741 m² 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 CO₂ and dyes with high adsorption capacity for CO₂ (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.

Keywords: carbazoles; dye adsorption; fluorescence; nitroaromatic sensing; silsesquioxane.
