A D–π-A structure near-infrared fluorescent probe (Lyso-BTC) is explored for its fluorescence visualization and detection of lysosomes in view of a large Stokes shift (∼190 nm), NIR emission (685 nm), excellent photostability, fluorescence response to viscosity, and lysosome-targeted property.
A near-infrared (NIR) fluorescent probe with a large Stokes shift (143 nm) for the rapid identification of Cys over Hcy and GSH in aqueous solution was developed.
