Tetra-armed conjugated microporous polymers for gas adsorption and photocatalytic hydrogen evolution

Two novel null tetra -armed conjugated microporous polymers with different geometries have been designed and synthesized via Suzuki-Miyaura cross coupling polycondensation. Both polymers are stable in various organic solvents tested and are thermally stable. The pyrene-containing polymer of PrPy with the rigid pyrene unit shows a higher Brunauer-Emmet-Teller specific surface area of null 1219 m2 g−1 null than the tetraphenylethylene-containing...
