Electrically Tunable Hysteretic Photonic Gels for Nonvolatile Display Pixels

Plastic pixels: Electrically tunable photonic pixels exhibiting nonvolatile photonic colors are demonstrated by coupling the hysteretic optical properties of PS-b-P2VP block copolymer photonic gels with an electrochemically induced pH gradient. The optical volatility of photonic pixels was tuned by controlling the hysteresis strength and the conversion pH value, which were both highly dependent on the species of anions pairing with pyridinium groups.
