| 中文摘要: |
| 本文通过将苯并咪唑衍生物1,4-双(2-苯并咪唑基)苯（H）作为客体分子，Q[8]作为主体分子混合后超声处理成功构建了H@Q[8]络合物，通过核磁共振氢谱和荧光光谱等表征手段研究了H和Q[8]之间的主客体包结行为。随后探究了H@Q[8]对庆大霉素（GEN）的荧光检测性能，发现其通过竞争包结导致H@Q[8]荧光增强，实现对GEN的选择性识别，同时展现出了良好的抗干扰性、快速的响应和低检测限（0.17 μmol/L）。 |
| 英文摘要: |
| H@Q[8] complex has been successfully constructed by a simple method, and the host-guest inclusion behavior between 1,4-bis (2-benzimidazolyl) benzene (H) and Q[8] has been studied by means of hydrogen NMR spectroscopy and fluorescence spectroscopy. Subsequently, the fluorescence detection of gentamicin (GEN) by H@Q[8] was investigated, and it was found that GEN induces fluorescence enhancement of H@Q[8] through competitive inclusion. This detection method has good anti-interference ability, fast response, and low detection limit (0.17 μmol/L). |
