enable it to function as a nanoprobe with ultralong NIR afterglow luminescence (up to 20 days) and ultrahigh tumor-to-liver signal ratio (up to 187) for in vivo deep-tissue afterglow imaging (with depth reaching 1.6 cm), in combination with chemiluminescence resonance energy transfer aided by active Schaap's dioxetane. Moreover, thanks to the excellent properties of the nanoprobe, the afterglow imaging-guided

pentazole ring. The unstable HN5/N5- produced at −40 °C did not build up in the solution but degraded to azide ion and nitrogen gas with a short lifetime. The 15N-labeling of the N3- ion obtained from all samples proved unequivocally that it came from the degradation of HN5 (tautomeric forms) and/or its anion N5- in the solution.
