| Anion Recognition Properties of Complex [Ru(phen)2(H2bbim)](PF6)2 |

| 摘要: 利用紫外-可见吸收光谱和核磁研究了[Ru(phen)2(H2bbim)](PF6)2配合物与Cl-，Br-，I-，NO3-，HSO4-，H2PO4-，OAc-和F-离子之间的作用。结果表明OAc-和F-可以使该配合物苯并联咪唑上的质子逐步脱去，相应的溶液颜色由黄色变为橙棕色，最后变为紫色。因此该配合物可以对阴离子实现目视识别。 |

| Abstract: Interactions between the complex [Ru(phen)2(H2bbim)](PF6)2 and Cl-, Br-, I-, NO3-, HSO4-, H2PO4-, OAc- or F- anion were studied by UV-Vis and 1H NMR spectra. A systematic investigation shows that stepwise deprotonation of the two N-H fragments occurs when OAc- or F- exits, resulting in color change from yellow to orange brown to purple, which can be distinguished by naked-eye. |
