Check out our latest work on visible to near-infrared (NIR) light responsive halochromic hydrazones, now out in Communications Chemistry as part of the Photoswitchable Materials collection! We show how the photophysics of hydrazone switches can be expanded to the NIR region using protonation as a secondary handle. Congrats to Shefali!
