Two Olefin-Linked Conjugated Microporous Polymers with Good Stability and Porosity for Carbon Dioxide Uptake

Conjugated microporous polymers (CMPs) are a novel kind of porous polymers with high-conjugated and micro-pore skeleton, achieving various functions. Due to the diversity of reactions and variety of building blocks, many synthetic methods have been used for the development of CMPs. Here, we have designed two olefin-linked OL-CMPs via the aldol condensation under solvothermal conditions. Both OL-CMPs showed high porosity and excellent stability. A high surface area of OL-CMP-1 was up to 945 m2 g-1 and micropore size was observed at 0.92 nm. The OL-CMP-1 and OL-CMP-2 indicated good carbon dioxide capture owing to their micropore skeleton and rich heteroatoms via the weak interaction. The olefin-linked conjugated microporous polymers (OL-CMPs) have been synthesized via the aldol condensation. Both OL-CMPs showed high porosity, excellent stability, and good carbon dioxide capture.image
