摘要：

In this paper, two novel benzothiazole derivatives EtSN and OAcSN with a D-pi-A configuration were developed as fluorescent probes for the detection of HSO3-. Compared with OAcSN, probe EtSN, bearing ester group, displayed a lower detection limit and faster response time. Upon treatment with HSO3-, EtSN and OAcSN displayed noticeable color change from yellow (EtSN)/red (OAcSN) to coreless, respectively. Competitive experiments indicated that EtSN and OAcSN had higher fluorescence selectivity towards HSO3- than other analytes. The sensing mechanism was further illustrated by H-1 NMR and TD-DFT.
