Used as a photochromic compound in smart materials and optical switches due to its reversible response to light exposure. Undergoes a change in molecular structure upon UV irradiation, resulting in a measurable shift in absorption, making it suitable for light-responsive sensors and molecular devices. Also investigated for use in organic electronics and as a building block in stimuli-responsive polymers. Its nitroaromatic groups enhance electron-accepting properties, useful in nonlinear optical (NLO) materials.
