摘要
A new probe based on the squaraine skeleton with a 2,4-dinitrobenzenesulfonyl unit is reported as a fluorescent probe for biothiol. It shows turn-on properties with red emission towards biothiols in acetonitrile-PBS buffer (1 : 9, v/v) solution, and its properties of rapid response, high selectivity and high sensitivity make it a potential probe with real applications. Moreover, the in vitro assays show that the probe can be used in fluorescence imaging for the detection of intracellular biothiol levels.
