Conjugated microporous polymers based on biphenylene for CO2 adsorption and luminescence detection of nitroaromatic compounds

Abstract

Conjugated microporous polymers have shown great potential applications in chemosensors, gas storage/separation, light-harvesting, and organic electronic materials. In this study, three novel conjugated microporous polymers based on biphenylene have been synthesized by the palladium-catalyzed Suzuki and Sonogashira–Hagihara cross-coupling reactions of 3,4′,5-tribromobiphenyl. N2 adsorption studies indicate that these polymers are porous, and the BET surface areas are 493, 1576, and 643 cm2 g−1 for CMP-LS1, CMP-LS2, and CMP-LS3, respectively. Amongst these synthesized CMPs, CMP-LS2 exhibits the highest CO2 adsorption capacity of 87.4 cm3 g−1 and reasonable CO2/N2 selectivity (27.9) and CO2/CH4 selectivity (5.6) at 273 K/1 bar. CMP-LS1 and CMP-LS2 exhibit blue luminescence in ethanol suspension. Furthermore, the fluorescence of CMP-LS1 and CMP-LS2 can be effectively quenched by PA with the KSV constants of 5.05 × 104 and 3.70 × 104 M−1, respectively. They can be used as luminescent sensors for detecting nitroaromatic compounds.
