Used as a highly effective photochromic compound in optical applications, particularly in the production of light-responsive materials. It exhibits rapid color change under UV light exposure, making it ideal for use in photochromic lenses, smart windows, and optical switches. Its strong fatigue resistance and clear color contrast between its activated and deactivated states enhance performance in rewritable optical storage media and sensors. Due to its thermal stability and solubility in common organic solvents, it is easily integrated into polymer matrices for coatings and films requiring dynamic light modulation.
