The detection of chemical or biological analytes upon molecular reactions relies increasingly on fluorescence methods, and there is a demand for more sensitive, more specific, and more versatile fluorescent molecules. We have designed long wavelength fluorogenic probes with a turn-ON mechanism based on a donor-two-acceptor π-electron system that can undergo an internal charge transfer to form new fluorochromes

Novel fluorogenic compounds designed such that upon a chemical event, compounds capable of emitting NIR light are generated, are disclosed. The compounds comprise two or more acceptor-containing moieties and a cleavable donor-containing moiety, being in complete pi-electrons conjugation and being such that no delocalization of pi-electrons is enabled. Also disclosed are fluorescent compounds generated upon subjecting the fluorogenic compounds to a chemical event (e.g., deprotonation). Also disclosed are uses of the fluorogenic compounds as NIR probed with a Turn-ON mechanism in monitoring presence and/or level of various analytes.
