Lanthanide-based luminescent probes TPR1 and TPR2 were developed for the detection of hydrogen peroxide (H2O2) in living systems. The chemoselective reaction of these boronate-protected probes with H2O2 resulted in an enhanced lanthanide sensitization and a 6-fold increase in luminescent intensity. TPR2 was utilized to measure the endogenous production of H2O2 in RAW 264.7 macrophages using time-gated luminescent spectroscopy.
