Herein, we report a fast (15 min) and solvent-free mechanochemical approach to polymers of intrinsic microporosity(PIMs) with high molecular mass and low polydipersity by solid grinding. The enhanced reaction efficiency results from the instantaneous frictional heating and continuously exposing active sites within those solid reactants.
