based on bithiophene coupled dimesitylborane (BMB‐1) was synthesized and characterized. BMB‐1 was used for colorimetric and turn‐on fluorescent sensing of cyanide (CN−) and fluoride (F−) ions, in the presence of other competitive anions in an aqueous (CH3CN–H2O) medium. BMB‐1 showed a hypsochromic shift (blue shift) with addition of CN− and F− ions in absorption studies. The lower detection level of
合成并表征了一种新型的基于联噻吩偶联的双二茂硼烷(BMB-1)的荧光化学传感器。BMB-1被用于比色和开启氰化物(CN的荧光检测- )和氟化(F - )离子,在其他竞争阴离子在水溶液(CH存在3 CN-H 2 O)平台。BMB-1显示出与另外CN的蓝移(蓝移)-和F -离子吸收研究。CN的下检测水平-和F -离子为1.37×10 -9和1.75×10 -9 分别男,。的BMB-1结合机制是基于亲核加成CN的-和F -在UV光下观察到的离子bithio部分到boranylmesitylene单元内部的电荷转移过渡,并且颜色的变化。傅立叶变换红外光谱,质谱和密度泛函理论计算进一步证实了这一结果。此外,BMB-1探针被发现是用于去除f的优良的吸附剂-使用吸附技术实际水样中的离子。
