Front Cover : The unique formation of a poly(pyrrole) (PPy) membrane, on the air/water interface of a droplet solution containing ammonium persulfate and phytic acid, is investigated in article number 1800707 by Sang Joon Lee and co‐workers. As polymerization occurs at the air/water interface, a blue‐black PPy clearly forms, and the top of the droplet becomes rapidly flattened. The surface of the fabricated PPy thin film has a well‐organized structure of a pretzel shape.
