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.
