Abstract

A near-infrared sensor for cyanide ion (CN^-) was developed via internal charge transfer (ICT). This sensor can selectively detect CN^- either through dual-ratiometric fluorescence (logarithm of I₄₁₄/I₅₆₄ and I₈₀₃/I₅₆₄) or under various absorption (356 and 440 nm) and emission (414, 564 and 803 nm) channels. Especially, the proposed method can be employed to measure β-glucosidase by detecting CN^- traces in commercial amygdalin samples.
