  • Luminescence properties of “double-stranded staircase” copper(i) halide coordination polymers with N-containing ligands
    作者:Jiri Pospisil、Inke Jess、Christian Näther、Marek Necas、Petr Taborsky
    DOI:10.1039/c0nj00809e
    日期:——
    A set of CuIXL coordination polymers (X = Cl, Br, I; L = derivatives of pyrazine and bipyridine) with double-stranded staircase structures was analyzed by X-ray crystallography and luminescence spectroscopy to find a relationship between the structure and luminescence properties of the polymers. Our measurements have proved that luminescence emission wavelengths varied between 500–750 nm, after the polymers were irradiated by light with a wavelength of 370 nm. Although each coordination polymer has shown different emission maximum, we observed several interesting trends related to the structure of the compounds. There is a clear correlation between the emission maxima and the halide size and/or Cu–X distance, respectively. On the other hand, the substitution of the ligand L (pyrazine derivatives, 4,4′-bipyridine) has no significant contribution to the emission spectra. This observation supports the theory that the halide to metal charge transfer (XMCT) plays a key role in the photoluminescence of staircase polymers.
    我们通过 X 射线晶体学和发光光谱学分析了一组具有双链阶梯结构的 CuIXL 配位聚合物(X = Cl、Br、I;L = 吡嗪和双吡啶的衍生物),以找到聚合物结构与发光特性之间的关系。测量结果表明,在波长为 370 纳米的光照射下,聚合物的发光波长在 500-750 纳米之间变化。虽然每种配位聚合物的发射最大值各不相同,但我们观察到了几种与化合物结构有关的有趣趋势。发射最大值分别与卤化物尺寸和/或 CuâX 间距有明显的相关性。另一方面,配体 L 的替换(吡嗪生物、4,4â²-联吡啶)对发射光谱没有明显影响。这一观察结果支持了卤化物到属的电荷转移(XMCT)在阶梯聚合物的光致发光中起关键作用的理论。
  • One- and Two- Dimensional Copper(I) Halide Based Coordination Polymers with Bridging Pyridazine or Pyrimidine Ligands

    日期:1999.9.1

    1-Dimensional coordination polymers 1 [CuX(μ-pydz)] 1 - 3 (X = Cl, Br, I; pydz = pyridazine) may be prepared by self-assembly in acetonitrile solution at 120 °C (1) or room temperature (2, 3). Individual chains contain (CuX)2 rings and dimeric [Cu(μ-pydz)]2 substructures. At a 2:1 molar ratio treatment of CuI with pydz in acetonitrile affords the lamellar complex 2 [(Cul)2(μ-pydz)] (4) whose novel 2 [(Cul)2] sheets contain fused 4-, 6- and 8-membered (Cul)n rings and are stabilized by pydz bridging between adjacent Cu atoms. In contrast,2 [(CuBr)2(μ-pym)2] (5) (pym = pyrimidine) contains separated 1 [CuBr] chains and (CuBr)2 rings as participating building units.

    1维配位聚合物[ CuX(μ-pydz)] 1 - 3 (X = Cl, Br, I; pydz = pyridazine) 可以在乙腈溶液中以自组装的方式在 120°C (1) 或室温 (2, 3) 下制备。单个链包含 (CuX)2 环和二聚体 [Cu(μ-pydz)]2 亚结构。在乙腈中以2:1的摩尔比处理 CuI 和 pydz 可以得到层状复合物[(Cul)2(μ-pydz)] (4),其新颖的[(Cul)2]片含有融合的 4-, 6- 和 8-成员环,并通过 pydz 在相邻 Cu 原子之间的桥接稳定。相比之下,[(CuBr)2(μ-pym)2] (5) (pym = pyrimidine) 含有分离的[CuBr]链和(CuBr)2环作为参与构建单元。
