Triarylboron-based fluorescent conjugated microporous polymers

Abstract

Novel triarylboron-based conjugated microporous polymers (BCMPs) were successfully synthesized and characterized, which are insoluble in common organic solvents and water, and can keep stable up to 310 °C under a nitrogen atmosphere. According to the nitrogen physisorption isotherms, the Brunauer–Emmett–Teller specific surface area values for these porous materials vary between 815 and 911 m² g⁻¹. Two polymer frameworks display good carbon dioxide uptake capacity at 273 K and 1 bar. These materials might find applications in organic electronics and sensing technologies.
