摘要
A novel BODIPY-based fluorescent thermometer, which shows a lysosome-targeting property, was successfully prepared. Due to the electron-donating ability of the oligo(ethylene glycols), the photoinduced electron-transfer pathway from morpholine to BODIPY dye is blocked. The fluorescence of the thermometer quenched by intramolecular rotation at room temperature was progressively enhanced during heating due to the increased microviscosity around the fluorophore.
