  Functionalized Gold Nanoparticles as Phosphorescent Nanomaterials and Sensors

  摘要：

  Ligand-capped gold nanoparticles were synthesized by capping monothiol derivatives of 2,2'dipyridyl onto the surface of Au nanoparticles (Au-BT). The average size of the metal core is around 4 nm, with a shell of similar to 340 bipyridine ligands around the Au nanoparticle. The high local concentration of the chelating ligands (similar to 5 M) around the Au nanoparticle makes these particles excellent ion sponges, and their complexation with Eu-lll/Tb-lll ions yields phosphorescent nanomaterials. Absorption spectral studies confirm a 1:3 complexation between Eul(lll)/Tb-lll ions and bipyridines, functionalized on the surface of Au nanoparticles. The red-emitting Au-BT:Eu-lll complex exhibits a long lifetime of 0.36 ms with six line-like emission peaks, whereas the green-emitting Au-BT:Tb-lll complex exhibits a lifetime of 0.7 ms with four line-like emission peaks. These phosphorescent nanomaterials, designed by linking BT:Eu-lll complexes to Au nanoparticles, were further utilized as sensors for metal cations. A dramatic decrease in the luminescence was observed upon addition of alkaline earth metal ions (Ca2+, Mg2+) and transition metal ions (Cu2+, Zn2+, Ni2+), resulting from an isomorphous substitution of Eu-lll ions, whereas the luminescence intensity was not influenced by the addition of Na+ and K+ ions. Direct interaction of bipyridine-capped Au nanoparticles with Cu2+ ions brings the nanohybrid systems closer, leading to the formation of three-dimensional superstructures. Strong interparticle plasmon interactions were observed in these closely spaced Au nanoparticles.

  is the first example of an allosteric recognition system, in which the same effector, that is, Fe(II), exhibits both large positive and negative allosteric effects on equilibrium and dynamic recognition events. The X-ray analysis and 1H NMR examination indicate that the combination of the macrobicyclic effect and the intramolecular interchain interactions (CH-pi interaction and steric hindrance) finely

  在超分子化学中，大量注意力集中在通过外部刺激调节客体结合上。然而，为了将相同的效应器用于高度客体选择性的正和负变构效应，需要对主体结构进行更严格和更精确的调节。一种新型变构宿主 1 与 Fe(II) 结合以提供假密码体 1.Fe(II)，它带有一个空腔，该空腔被三个聚醚链以螺旋方式包围。1 (Na+ > K+ > Rb+ > Cs+) 的结合选择性与 1.Fe(II) 相反（Cs+ > Rb+ > K+ > Na+）。通过液膜的单离子传输显示出与平衡常数相似的离子选择性。据我们所知，这是变构识别系统的第一个例子，其中相同的效应物，即 Fe(II)，对平衡和动态识别事件表现出巨大的正负变构效应。X 射线分析和 1H NMR 检查表明，大双环效应和分子内链间相互作用（CH-pi 相互作用和位阻）的结合可以很好地控制正负变构效应，这取决于客体的大小。螺旋框架开辟了一种新的通用方法，用于构建更复杂、可控的螺旋生物分子受体，例如

  interactions to direct transition-metal catalysis is a potentially powerful yet relatively underexplored strategy, with most investigations thus far focusing on using hydrogen bonds as the controlling element. We have developed an ion pair-directed approach to controlling regioselectivity in the iridium-catalyzed borylation of two classes of aromatic quaternary ammonium salts, leading to versatile meta-borylated

  使用非共价相互作用直接过渡金属催化是一种潜在的强大但相对未开发的策略，迄今为止大多数研究都集中在使用氢键作为控制元素。我们开发了一种离子对导向的方法来控制铱催化的两类芳族季铵盐的硼化反应中的区域选择性，从而产生多功能的偏硼化产物。通过检查一系列取代的底物，这提供了适合快速多样化的复杂的官能化芳香支架，并更广泛地证明了离子对在过渡金属催化中控制区域化学的可行性。

• <i>meta</i> -Selective C−H Borylation of Benzylamine-, Phenethylamine-, and Phenylpropylamine-Derived Amides Enabled by a Single Anionic Ligand

  Clever positioning: A bipyridine ligand incorporating a remote anionic sulfonate group directs iridium-catalyzed borylation to the meta-position on a range of amide-containing arenes. It is proposed that this selectivity is a result of a hydrogen bonding interaction to correctly position the iridium metal centre in the crucial C−H activation.

  A benzo-dipteridine (BDP) having a bipyridin-6-ylmethyl moiety oxidizes α-hydroxy acids to give α-keto acids in the presence of Zn2+ and Et3N in ButOH, whereas a BDP bearing a bipyridin-5-ylmethyl moiety is unable to oxidize them under the same conditions; this is the first example of a D-lactate dehydrogenase model.
