  摘要：

  By reaction of LiR and [AuCl(tht)] the new organometallic compounds NBu4[AuR2] (R = 2-C6BrF4 (1), 2-C6F4I (2)) have been prepared. They react with TlPF6 in different molar ratios yielding anionic extended chains with the stoichiometries {NBu4[Tl-2(AuR2)(3)]}(n), (R = 2-C6BrF4 (3), 2-C6F4I (4)) and {NBu4[Tl(AuR2)(2)]}(n) (R = 2-C6BrF4 (5), 2-C6F4I (6)). The crystal structures of 3 and 4 consist of anionic chains formed by association of loosely bound Au2Tl2 clusters interconnected by [AuR2](-) anions via unsupported Au center dot center dot center dot Tl interactions, while 5 shows infinite polymetallic Au/Tl chains with an additional [AuR2](-) fragment bonded to each Tl-1 via unsupported Au center dot center dot center dot Tl contacts. The heterometallic bromotetrafluorophenyl complexes 3 and 5 display luminescence in the solid state, which is assigned to excited states that appear as result of the interactions between the metal centers. At 77 K different emissions appear in glassy solutions, which are assigned to the presence of oligomers of different length. In the case of the iodotetrafluorophenyl derivatives, in spite of presenting similar structures, complex 4 is weakly luminescent and complex 6 is nonluminescent both in the solid state at room temperature and at 77 K and in glassy solutions. This result is probably a consequence of the heavy-atom effect (HAE) due to the presence of iodine instead of bromine, which in the case of complex 4 provokes a reduction of the intensity if compared with its homologous compound 3 and which in 6 leads to the total quenching of the emission.

  strongly luminescent materials with tunable emission, we utilized the propensity of the robust bimetallic clusters [Au₂Ag₂(R(I)/R(II))₄] (R(I) = 4-C₆F₄I, R(II) = 2-C₆F₄I) for self-assembly through aurophilic interactions. With a de novo approach that combines the coordination and halogen-bonding potential of aromatic heteroperhalogenated ligands, we have generated a family of remarkably luminescent bimetallic

  为了在寻求具有可调发射的强发光材料的背景下开发新架构，我们利用了稳健的双金属簇 [Au₂Ag₂(R(I)/R(II))₄] (R(I) = 4-C₆F₄I，R(II) = 2-C₆F₄I) 用于通过亲热相互作用进行自组装。通过结合芳香杂全卤化配体的配位和卤素键合潜力的从头方法，我们产生了一系列显着发光的双金属材料，为解决潜在的两种相互作用的相关性、相对效应和协同作用提供了基础。光物理学。通过将发绿光 (λ(max)(em) = 540 nm) 的单体 [Au₂Ag₂R(II)₄(tfa)₂]²⁻ (tfa = trifluoroacetate) 聚合成发红光的 (λ(max)(em) = 660 nm) 聚合物 [Au₂Ag₂R(II)₄(MeCN)₂](n)，我们在此证明，这些材料中的簇缔合程度可以通过在固态下施加机械化学和/或蒸气化学刺激以及在溶液中通过溶剂化化学而有效且可逆地转换，反应与强烈的剧烈转换同时发生。
