Abstract
Formation of the ensemble between the anthracene base dinuclear Cu (II) complexes (Cu2L) with pyrogallol red (PGR) were studied, with the aim to exploit the determination of cyanide (CN-). The experiments were carried out in an aqueous solution of 80/20 (%v/v) CH3CN/H2O in the presence of 10 mM HEPES buffer pH 7.4. It was found this ensemble could sense CN- selectively by changing the blue color of ensemble to colorless. The sensing process is based on the nucleophilic addition of CN- to bounded PGR in the ensemble structure.
