一种高选择性的银的荧光探针
Selective Fluorescent Recognition to Silver ion
合成了3,3,7,7-四[N-乙基-N-苄基(乙酰胺)-2-氧甲基]-5-氧基壬烷 (EBAOO)及其铽的配合物，配合物的单晶结构如下：[Tb(EBAOO)]2[Tb(NO3)5]3•H2O，正交晶系，a = 40.722 (6) Å, b = 18.418 (3) Å, c = 20.496 (3) Å。在这个结构中，稀土离子满足九配位构型。根据二面角和最小二乘平面讨论了这种九配位的多面体。配合物的荧光强度随着Ag+的配位而显著增加，这是由于光诱导电子转移效应（PET）的抑制。因而铽配合物可以作为一种高选择性的银的荧光探针。
We have synthesized 3,3,7,7-tetra[N-ethyl-N-benzyl(acetamide)-2-oxymethyl]-5- oxanonane (EBAOO) and its terbium complex. The crystal structures of the complex were determined: [Tb(EBAOO)]2[Tb(NO3)5]3•H2O, Orthorhombic, a = 40.722 (6) Å, b = 18.418 (3) Å, c = 20.496 (3) Å. In the structure, the rare earth ion satisfies nine coordination. The geometry of the nine-coordinate polyhedron is discussed in terms of the dihedral angle and the mean plane. The luminescence of the complex is noticeable enhanced upon complexation with Ag+, which is due to the suppressing of photoinduced electron transfer (PET) process. Therefore, the terbium complex can be the generation of silver selective fluorescent probe.
