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.
通过分子内电荷转移(ICT)开发了一种用于氰离子(CN(-))的近红外传感器。该传感器可以通过双比率荧光(I414/I564和I803/I564的对数)或在各种吸收(356和440 nm)和发射(414、564和803 nm)通道下选择性地检测CN(-)。特别是,所提出的方法可用于通过检测市售苦杏仁苷样品中的CN(-)痕量来测量β-葡萄糖苷酶。
