The fabrication of single‐crystalline thin‐film arrays for an organic ferroelectric small molecule is achieved by a simple solution process without additional thermal annealing. Based on a cooperative proton tautomerism through a hydrogen‐bonding network, films show the polarity switching with an operating voltage of less than 5 V at room temperature. This approach provides a low‐cost and eco‐friendly fabrication of ferroelectric devices.
