| Research Abstract |
Tuning the optical properties of luminscent materials by external stimuli has been intensively studied because of their ability for various devices, such as sensors and optical media. However, practical example of changing optical properties by light stimuli is challenging. In this context, we prepared organic crystals from anthracenedisulfonic acids and photochromic thymine arranges and reversibly modulate optical properties by UV irradiation. The organic salt can incorporate several organic solvents and emits various fluorescence depending on guest solvents.
