Cyanide detecting porphyrin fluorescent sensors: Effects of electron-donating/withdrawing substituents

A reaction based carbazole–indolium conjugate probe for the selective detection of environmentally toxic ions

“…The interaction of binding was calculated by using the B – H equation, as reported. 37–44 The calculated value was 1.38 × 10 8 M, which indicates the strong binding by the cyanide ion with the synthesized probe molecule. The plot of the B – H equation is given in Fig.…”
