Membranes with high permeability to gases are formed from polyimides with rigid backbones that incorporate a spiro‐centre (see figure). A route to this new range of high‐free‐volume polyimides is demonstrated, and exceptional performance is obtained for a polymer containing a dimethyl binaphthyl unit.
