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.
