Abstract :Hydrogen sulfide (H2S) is a biologically relevant gaseous molecule, which involves in a wide variety of physiological and pathological processes. Thus, detection of H2S is highly valuable in order to clarify its complex roles. In this study, a new benzothiazole-based donor-acceptor type H2S selective chemodosimeter (HP-1) was synthesized and its H2S detection capabilities were investigated in aqueous solutions. HP-1 exhibited a red-shifted absorption signal at 530 nm and a near-infrared (NIR) fluorescence peak at 680 nm as a result of enhanced intramolecular charge transfer (ICT) in the presence of H2S, which enabled a selective and very rapid ratiometric fluorescent detection. HP-1 was also showed to be highly sensitive toward H2S with a very low limit of detection value.Keywords : Fluorescence, hydrogen sulfide, benzothiazole, near-infrared imaging, chemodosimeters
