Fluorescent molecules that absorb and emit light in the near-infrared (NIR) and short-wave infrared (SWIR) regions have significant potential for various applications. These molecules can serve as ...

Ultrasound‐switchable fluorescence (USF) imaging combines the deep penetration and spatial selectivity of focused ultrasound with the high sensitivity and specificity of fluorescence detection. By ...

Redox-active triphenylamine-appended pyrazinacenes show extreme reversible redox-coupled switching of their photophysical properties. In their reduced state, absorption and emission bands fall well ...
