2,3,5,6-Tetrabromo-8-phenyl BODIPY as a fluorometric and colorimetric probe for amines

The usability of 2,3,5,6-tetrabromo-8-phenyl BODIPY (BrBDP) for colorimetric/fluorimetric determination, discrimination, and quantification was investigated. The addition of an amine compound to the solution of BrBDP in acetonitrile caused dramatic changes in the photophysical properties and the color of the solution. These observed changes were specific to the structure of the amine, giving the chemodosimeter the ability to distinguish amines based on their structural properties Other tested functional groups (ethanol, phenol, acetone, formaldehyde, DMF, diethyl ether, ethyl acetate, and acetic acid) resulted in minimal or no change in the photophysical properties of the chemodosimeter indicating it to be highly selective. BrBDP-adsorbed TLC plates were shown to be used as test strips for the detection of volatile amines. Biogenic amines released from spoiled chicken meat were detected by this test strip.

Automated summary

The usability of BrBDP in colorimetric/fluorimetric determination, discrimination, and quantification was investigated, revealing its ability to distinguish amines based on their structural properties. The chemodosimeter showed high selectivity towards tested functional groups and could be used for detecting volatile amines. Furthermore, it was proven to be effective in detecting biogenic amines released from spoiled chicken meat.
