摘要
以2-萘硼酸为原料,电化学合成得到一种碘离子荧光探针(NPS),NMR和LC-MS确证了其化学结构.光谱测试结果表明,NPS能高选择性地识别I-,有较强的专一性,且识别过程不受其他阴离子的影响,有较强的抗干扰能力.同时,探针NPS对I-具有较高的检测灵敏度,最低检出限为170.39 nmol/L.此外,该探针能够在酸性到弱碱性的范围内稳定地检测I-,应用范围广,可用于实际水样中I-检测.综上所述,该探针的合成对未来I-的识别和应用具有较强的参考价值.
Abstract
A iodine ion fluorescent probe(NPS)was synthesized by electrochemical synthesis based 2-naphthylboronic acid as raw material.The chemical structure of the probe was confirmed by NMR and LC-MS.The spectral test showed that NPS can recognize I-with high selectivity.Moreover,the recognition was not affected by other anions and had strong anti-interference ability.Meanwhile,the probe NPS had also high detection sensitivity to I-.The detection limit was 170.39 nmol/L.In addition,the probe can stablydetect I-in the range from acidic to alkalescent,and has a wide range of applications,which can be used for I-detection in actual water samples.In summary,the synthesis of the probe has a strong reference value for the identification and application of I-in the future.
