Dynamic Fluorescence Modulation via Light‐Driven Competitive Protonation
Advanced Optical Materials, EarlyView.A two‐component molecular system demonstrates reversible, light‐driven fluorescence write–erase cycling and thermal imaging. Illumination of a merocyanine photoacid transfers a proton to a highly efficient fluorescent pyridinium dye, switching its emission color; thermal relaxation reverses the process in the dark.

Transparent Single‐Dye NIR Photonic Platform for Multimodal Optical Authentication
Advanced Optical Materials, EarlyView.A single‐component DHP‐SQ dye integrates visible transparency, near‐infrared (NIR) fluorescence, and photothermal functionality into one molecular platform. NIR‐selective visualization transforms visually imperceptible printed patterns into readily authenticated information, while screen‐printing compatibility enables well‐defined patterning on diverse
