Here, a reversible redox probe REPOMs emitting beyond 1500 nm is proposed to fill the blank, using rare earth ions-doped nanoparticles as emitter, and molybdenum-based polyoxometalate nanoclusters as the ROS-recognition site and emission modulator.  REPOMs exhibited excellent response towards the repeated cycle between ROS and glutathione, based on which the time-resolved ROS changes during HIRI were successfully obtained.
