A novel Off‐On type FRET‐based fluorescent nanoprobe, mainly consisting of the energy‐donating conjugated polymer poly(9,9‐dioctylfluorenyl‐2,7‐diyl and energy‐accepting 1 O 2 indicator 3‐diphenylisobenzofuran, was prepared for monitoring intracellular 1 O 2 during photodynamic therapy. Under visible excitation or even NIR two‐photon excitation, the initially non‐fluorescent nanoprobe lit up in the presence of 1 O 2 . This FRET‐based strategy is very promising for construction of fluorescent nanoprobes for other reactive oxygen species (ROS).
