  • A highly selective fluorescent probe based on Michael addition for fast detection of hydrogen sulfide
    作者:Baozhen Gao、Lixia Cui、Yong Pan、Minjie Xue、Boyu Zhu、Guomei Zhang、Caihong Zhang、Shaomin Shuang、Chuan Dong
    DOI:10.1016/j.saa.2016.09.051
    日期:2017.2
    4-hydroxy-1,8-naphthalimide-based compound (probe 1) has been designed and synthesized. The colorimetric and fluorescent properties of probe 1 towards hydrogen sulfide (H2S) were investigated in detail. The results show that the probe 1 could selectively and sensitively recognize H2S rather than other reactive sulfur species. The reaction mechanism of this probe is an intramolecular cyclization caused
    一种新的基于4-羟基-1,8-二甲酰亚胺的化合物(探针1)已经被设计和合成。详细研究了探针1对硫化氢(H 2 S)的比色和荧光性质。结果表明,探针1能够选择性地并且灵敏地识别H 2 S,而不是其他反应性物质。该探针的反应机理是由于H 2 S的迈克尔加成而产生4-羟基-1,8-二甲酰亚胺的分子内环化。4-羟基-1,8-二甲酰亚胺的分子内电荷转移是重要的。探针1快速响应H 2 S,并在5分钟内显示出75倍的荧光增强。此外,探针1可以检测H 2S的定量检测限低至0.23μM。

  • Reaction Based Fluorescent Probes for Hydrogen Sulfide
    作者:Chunrong Liu、Bo Peng、Sheng Li、Chung-Min Park、A. Richard Whorton、Ming Xian
    DOI:10.1021/ol3008183
    日期:2012.4.20
    A reaction based fluorescence turn-on strategy for hydrogen sulfide (H2S) was developed. This strategy was based on a H2S-specific Michael addition-cyclization sequence. Other biological thiols such as cysteine and glutathione did not pursue the reaction and therefore did not turn on the fluorescence/consume the substrates. The probes showed good selectivity and sensitivity for hydrogen sulfide.
