A new visual bis(salamo)-based fluorescent chemosensor for detection of B 4 O 7 2− in environmental and biological systems was synthesized for the first time by Schiff base reaction. The bright blue fluorescence of the sensor and B 4 O 7 2− was very obvious and the limit of detection for B 4 O 7 2− was as low as 6.97 × 10-10 M. Importantly, the first attempt of exogenous detection in zebrafish gained success. • H 6 L was explored for detecting B 4 O 7 2−. • It can be used for detection in zebrafish. A newly synthesized fluorescent chemosensor H 6 L was explored for detecting B 4 O 7 2−, characterized by 1H NMR spectrum, mass spectrum and fluorescence spectra. During the detection process of B 4 O 7 2−, the fluorescence is significantly enhanced and naked eye recognition can be performed under 365 nm UV light without any interference by other typical anions. The limit of detection is as low as 6.97 × 10-10 M. In addition, in order to broaden the application of salamo-based fluorescence sensors in the field of biology, except for the fluorescence imaging of HeLa cells, the first attempt of exogenous detection in zebrafish was conducted successfully.
