Chemically active polyelectrolyte planar defects (see Figure) are embedded into colloidal photonic crystals using both direct‐coating and transfer‐printing techniques. These planar defects introduce a transmitting state within the photonic stop band, which is dynamically adjusted with nanometer precision by pressure‐controlled selective vapor sorption.
