Excited-state intramolecular proton transfer (ESIPT) has received considerable attention due to the characteristic four-level photophysical scheme incorporating the ground and excited states of two different tautomers of enol and keto forms. Different absorbing and emitting molecular species in this ESIPT cycle normally result in the total exclusion of self-absorption and the large Stokes’ shifted keto emission. Based on these unique and beneficial photophysical properties, ESIPT molecules are gaining interest for potential applications in organic light emitting diodes, photo-patterning, chemosensor, proton transfer laser, and photostabilizer. Fine control of the functional substituents as well as the molecular structure of core ESIPT unit is primarily demanded for specific applications. Here, we report the enhanced photoluminescence and the photo-physical properties of benzoxazole derivatives appropriate for the field of fluorescence labeling. |
