Polymers with intrinsic microporosity
WebIn this work we used betulin as a rigid monomer to synthesize polyesters with intrinsic microporosity, which are made from at least 75 wt.-% of renewable materials. The stiff structure of betulin prevents close packing of the polymer chains. Betulin can be used as a raw material for polyester networks as well as for linear, soluble polymers ... WebOne of these polymers of intrinsic microporosity, P38, showed the highest sacrificial hydrogen evolution rate of 5226 μmol h −1 g −1 under visible irradiation ( λ > 420 nm), with an external quantum efficiency of 18.1% at 420 nm, placing it among the highest performing polymer photocatalysts reported to date for this reaction.
