Structures of Metal-Organic Frameworks with Rod Secondary Building Units
33次浏览
Alexander Schoedel, Mian Li, Dan Li, Michael O’Keeffe,* and Omar M. YaghiAbstract:Rod MOFs are metal−organic frameworks in which the metal-containing secondary building units consist of infinite rods of linked metal-centered polyhedra. For such materials, we identify the points of extension, often atoms, which define the interface between the organic and inorganic components of the structure. The pattern of points of extension defines a shape such as a helix, ladder, helical ribbon, or cylinder

Curved Cyclic Trimers: Orthogonal Cu–Cu Interaction versus Tetrameric Halogen Bonding
34次浏览
Xiao-Liang Wang, Ji Zheng, Mian Li, Seik Weng Ng, Sharon Lai-Fung Chan and Dan Li*Abstract:In this work, two polymorphs and a pseudopolymorph of a trinuclear copper(I) pyrazolate complex, namely,[Cu(L-Br)]3 (L-Br = 4-(4-bromophenyl)-3,5-dimethylpyrazolyl), were isolated. One of them shows remarkable molecular shape curving, which is imposed by short intermolecular CuI−CuI interaction and parallelogram-like Br4 halogen bonding. These two sets of noncovalent interactions propagate along different

Exceptionally water stable heterometallic gyroidal MOFs: tuning the porosity and hydrophobicity by doping metal ions
47次浏览
Xiao-Wei Zhu, Xiao-Ping Zhou, and Dan Li*Abstract:A strategy to improve the framework porosity and hydrophobicity of the pore surface by doping metal ions (Cu2+, Cd2+, or Fe2+) into a gyroidal MOF STU-1 has been developed. It is found that the obtained heterometallic MOFs are exceptionally water stable.文章链接:C6CC02116F.pdf

极长与极短的铜铜距离-吡唑环三核亚铜配合物亲铜作用本质及发光调控
26次浏览
郑霁,邢立锐,李丹*摘要:本文结合近年来亲金属作用研究领域的进展,针对本课题组在环三核亚铜配合物方面的最新研究成果讨论了两个铜(I)–铜(I)作用相差悬殊的体系。一是通过构筑具有环三核单元的三棱柱笼状配合物,确认在正堆积模式下即使环三核单元之间亲铜作用极弱依然可以在磷光发射态中产生强亲铜作用,且通过配体的预留配位点与Cu2I2簇连结从而得到自校准大范围发光温度计;二是通过与亲铜作用正交的Br―Br卤键,实现环三核亚铜配合物前所未有的极短铜(I)–铜(I)距离,通过各种电子结构分析方法研究其本质。结果表明即使当铜(I)–铜(I)距离很接近铜的范德华半径和时,其本质依然为闭壳层作用,而Br―Br作用总为闭壳层作用,且该体系中最强的Br―Br作用很好地体现出一个Br原子的σ穴和另一个Br原子的负静电势区域的匹配性。关键词:亲铜作用;正堆积;磷光发射态;卤键;约化密度梯度;分子中的原子的量子理论文章链接:PKU.WHXB201706051.pdf

Structure- and Temperature-Dependent Luminescence Properties of Threefold Interpenetrated Networks: Coordination Polymers Based on Dinuclear Gridlike Silver(I) Units

Shun-Ze Zhan,* Huan-Quan Song, Liu-Jun Guo, Raymond Wai-Yin Sun, and Dan Li*Abstract:Dinuclear gridlike AgI structural units (1) based on(3-pyridyl)-5-R-pyrazole ligands are extended from ligomers(R = phenyl) to three threefold interpenetrated 3D coordinationpolymers (R = 3-pyridyl) with cds-a (augmented CdSO4) networks(2-NO3, 2-ClO4, 2-BF4) linked through multiple supramoleculainteractions (Ag–ligand, Ag–anion, Ag···Ag, and π–π interactions). The photoemission intensities of 2-NO3, 2-ClO4,and 2
