A novel cyanobiphenyl benzothiazole-based fluorescent probe for detection of biothiols with a large Stokes shift and its application in cell imaging

An ESIPT-based fluorescent probe with a large Stokes shift (202 nm) for the sensing of biothiols has been developed based on cyanobiphenyl benzothiazole derivative exhibiting larger Stokes shift than 2-(benzothiazol-2-yl)phenol.116
