摘要
Chemiluminescence,a phenomenon emitting light from chemical reactions rather than photon absorption,has gained significant interest for applications in bioimaging and biosensing due to its high sensitivity and low background interference.Now there is a growing interest in near-infrared(NIR)chemiluminescent probes for improved tissue penetration and reduced autofluorescence.This review summarizes NIR emissive chemiluminescent probes based on 1,2-dioxetane and discusses their chemical structures and applications.Structure modification strategies for red-shifting wavelength and enhancing brightness include incorporating electron-withdrawing groups,designing chemiluminophore-fluorophore cassettes,and exploring alternative chemiluminescent scaffolds.This review aims to inspire the exploration of NIR chemiluminescent probes in disease detection and treatment.
