Effective separation of hexaphenylbenzene from n‐heptane is demonstrated on page 4729 by A. G. Livingston and co‐workers. Ultrathin and free‐standing polymer films with intrinsic microporosity (PIM‐1) are precisely fabricated on porous substrates. The organic solvent nanofiltration performance with exceptionally fast permeation of n‐heptane through PIM‐1 layers down to 35 nm in thickness are presented. Membranes show highly non‐monotonic performance with film thickness and ageing resistance.
