Abstract :Hydrogen sulfide insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(NIR); fluorescence peak at 680 nm as a result of enhanced intramolecular charge transfer insert ignore into journalissuearticles values(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.
