The functionalization of three-dimensional (3D) covalentorganicframeworks (COFs) is essential to broaden their applications. However, the introduction of organic groups with electroactive abilities into 3D COFs is still very limited. Herein we report the first case of 3D tetrathiafulvalene-based COFs (3D-TTF-COFs) with non- or 2-fold interpenetrated pts topology and tunable electrochemical activity
三维 (3D) 共价有机框架 (COF) 的功能化对于扩大其应用至关重要。然而,将具有电活性能力的有机基团引入到 3D COF 中仍然非常有限。在此,我们报告了具有非或 2 倍互穿 pts 拓扑和可调电化学活性的 3D 四硫富瓦烯基 COF(3D-TTF-COF)的第一个案例。获得的 COF 显示出高结晶度、永久孔隙率和大比表面积(高达 3000 m2/g)。此外,这些基于 TTF 的 COF 具有氧化还原活性,可通过碘掺杂形成有机盐,该盐具有可调节的电导率(在 120 °C 时高达 1.4 × 10-2 S cm-1)。这些结果为设计 3D 电活性 COF 材料开辟了道路,并促进了它们在分子电子学和能量存储中的应用。

enforce an inclusioncompound of 4 with a single, extremely hollow diamond-like host lattice by offering still bulkier guest molecules have as yet not been met with success. The generally very high propensity of 4 to form inclusioncompounds was envisaged and designed beforehand by appropriate evaluation and modulation of the crystal structure of the parent adamantane-1,3,5,7-tetracarboxylic acid, which

A self-adjusting metal–organicframework has been proposed for capturingtrace Xe and Kr from the nuclear reprocessing off-gas. The self-adjusting behavior endows ATC-Cu the highest Xe and Kr capacity at 0.1 bar and 298 K, as well as a benchmark for capturing low concentration Xe and Kr. The mechanism of the self-adjusting behavior has been studied through single-crystal X-ray diffraction experiments
已经提出了一种自调节金属有机框架,用于从核后处理废气中捕获痕量 Xe 和 Kr。自调节行为赋予 ATC-Cu 在 0.1 bar 和 298 K 下的最高 Xe 和 Kr 容量,以及捕获低浓度 Xe 和 Kr 的基准。通过单晶X射线衍射实验和计算计算研究了自调节行为的机理。

The syntheses and spectral characteristics of four-directional spherical dendritic macromolecules utilizing an adamantane core have been described. The dendrimer syntheses utilized 4-amino-4-(3-acetoxypropyl)-1,7-diacetoxyheptane or di-tert-butyl 4-amino-2-[(tert-butoxycarbonyl)ethyl]heptanedioate as the key building block. An improved synthetic procedure to 1,3,5,7-adamantanetetracarboxylic acid is reported.
