Benzo‐15‐crown‐5 functionalized polymer brushes prepared via surface‐initiated atom transfer radical polymerization are used as the active layer in a potassium‐selective quartz crystal microbalance sensor. The polymer brushes allow the selective detection of potassium ions, even in the presence of a large excess of sodium ions and the sensitivity of the sensor can be tuned by varying the brush thickness.
