A novel metalloporphyrin-based conjugated microporous polymer for capture and conversion of CO2

Abstract

A novel conjugated microporous polymer was solvothermally synthesized using an aluminum porphyrin as a main building block, which had a high Brunauer–Emmett–Teller specific surface area up to 839 m² g⁻¹ and a pore volume of 2.14 cm³ g⁻¹. The polymer displayed excellent capacity to capture carbon dioxide (4.3 wt%) at 273 K and 1 bar, and good catalytic activity for cyclic carbonate synthesis with TOF up to 364 h⁻¹.
