We have shown how the nucleophilic ring opening of the triazolopyridinium salts can be used in sensing applications. The reaction with cyanide yields highly emissive tetrazole derivatives that enable the quick, selective and efficient detection of the analyte. We are currently looking into ways to take advantage of this novel reaction, and the water-solubility of the triazolopyridinium (TOP) dyes in other sensing applications.

The modularity and solid-state emission of the BODIHY dyes allowed us to use them as solid-state acid and base sensors. A simple sensor built using TLC plates enabled us to use these compounds in detecting fish spoilage.
