Description 959-972
The synthesis and photophysical properties of a novel pyrimido fused benzothiazole-tetraphenylethene (TPE-1)
chromophore, incorporating both electron-donating (–SCH3) and electron-withdrawing (–CN) groups, are reported.
TPE-1 exhibits aggregation-induced emission (AIE), mechanochromic, and electrochemical characteristics. The recognition
behavior of TPE-1 towards various metal cations is investigated by fluorescence spectroscopy. TPE-1 shows a selective and
sensitive response towards ferric (Fe3+) ion over other tested cations in DMSO: water (90:10, v/v ratio) with a limit of
detection of 102 nM. Time-correlated single photon counting (TCSPC) plot displays dynamic and static quenching of
TPE-1 with the addition of Fe3+ ions. Computational studies have been performed to demonstrate the binding mode of TPE-
1 towards Fe3+ ions. Most importantly, the application of TPE-1 in the detection of Fe3+ ions in various water sources
showcases its promising utility in environmental monitoring and pollution control, underscoring its potential for substantial
contributions to environmental chemistry and sensor technology.
