cylindrical macrotricyclichost 1 containing an anthracene unit and two dibenzo [24]crown-8 moieties was synthesized, and its cation binding properties were studied. It was found that the host could not only form complex with the paraquat derivative 4, but also show selective templated complexation with pyromellitic diimide 2 and anthraquinone 3 in the presence of lithium and potassium ions, respectively
electrochemical performance of most reported CPF‐based MSCs. Especially, the device exhibited alternating current (AC) line filtering performance (−84.2° at 120 Hz) and a short resistance capacitance (RC) constant of 0.08 ms. This work not only provides a new CPF for MSCs with AC line filtering performance but also paves the way for thin‐film CPFs preparation with versatile applications.
配位聚合物骨架(CPF)由于其出色的功能(包括稳定的结构,固有的孔隙率等)而具有广泛的应用。但是,由于导电基材和CPF之间的相容性差以及薄膜制备的关键条件,制备用于能量存储和转换的薄膜CPF仍然是一个挑战。在这项工作中,通过在液-液界面处的各向异性四臂配体和Cu II的配位制备了CPF膜。这种基于薄膜的微型超级电容器(MSC)是通过高能划线和电解质浸泡制成的。预制的MSC表现出121.45 F cm -3的高体积比电容。此外,MSC的体积能量密度达到52.6 mWh cm -3超过了大多数报道的基于CPF的MSC的电化学性能。特别是,该器件具有交流(AC)线路滤波性能(在120 Hz时为-84.2°)和0.08 ms的短电阻电容(RC)常数。这项工作不仅为具有交流线路滤波性能的MSC提供了一种新的CPF,而且为制备具有多种用途的薄膜CPF铺平了道路。

The metalloid-centered covalentorganicframework has attracted great interest from both its structure and application. Heavier elements have seldomly been incorporated in the covalentorganicframeworks, even if they exhibit special structural features and properties. Herein, we reported the first crystalline germanate covalentorganicframework with hexacoordinated germanate linked by an anthracene
以准金属为中心的共价有机骨架从其结构和应用上都引起了极大的兴趣。即使较重的元素表现出特殊的结构特征和性质,也很少被引入共价有机骨架中。在本文中,我们报道了第一个具有蒽配位键连接的六配位锗酸酯的结晶锗酸酯共价有机骨架。骨架中抗衡离子锂离子的存在提供了在273 K下88.5 cm3 g-1的高CO2吸收和101的高 / N2选择性。在室温下观察到锂离子电导率显着提高了0.25 mS cm-1由于锗中心偏软。
Metal–Metal Interactions in Dinuclear (triphos)Cobalt Complexes Exhibiting Mixed Valency
properties of a series of dinuclear mixed-valence complexes containing two (triphos)Co units are reported: [(triphos)Co(L)Co(triphos)]+ (L = C6O4X2; × = H, Cl, Br, I, Me: 2a–e+; L = C14H4O4Me2: 4+). Complexes 2a–e+ are bridged by tetraoxybenzene ligands and exhibit very strong metal–metalinteraction leading to delocalized class-III behaviour while in 4+ the extended tetraoxoanthracence bridging ligand leads
