Revisiting β-dicyanovinyl substituted calix[4]pyrrole : toward the highly selective detection of hydrazine in solution

Résumé

The selective detection and quantification of hydrazine, a hazardous pollutant commonly used in industries, was performed by UV-spectroscopy with a repurposed β-dicyanovinyl substituted calix[4]pyrrole as chemosensor. Selectivity was evaluated in acetonitrile towards various nitrogen-containing compounds and a nucleophilic thiol. Moreover, influence of several parameters (time, water content and temperature) on hydrazine detection of the chemosensor was evaluated. This work allows the sensing of hydrazine with a LOD of 1.3 mg/L and a linear response on the 40-1000 μM range. Naked eye detection was also performed.
