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

Popis výsledku v původním jazyce

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. N-2 adsorption studies indicate that these polymers are porous, and the BET surface areas are 493, 1576, and 643 cm(2) 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 cm(3) g(-1) and reasonable CO2/N-2 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 K-SV constants of 5.05 x 10(4) and 3.70 x 10(4) M-1, respectively. They can be used as luminescent sensors for detecting nitroaromatic compounds.
