2015年2月25日 · We demonstrate that linkers with distinct lengths and functionalities can be sequentially installed into PCN-700. Single-crystal to single-crystal transformation is realized so that the positions of the subsequently installed linkers are pinpointed via single-crystal X-ray diffraction analyses.

2016年6月25日 · In addition, a size-selective catalytic system for aerobic alcohol oxidation reaction is built in PCN-700 through linker installation, which shows high activity and tunable size selectivity. Altogether, these results exemplify the capability of the linker installation method in the pore environment engineering of stable MOFs with multiple ...

2024年5月22日 · In this work, we developed a new MOF-based enantioselective sensing material, PCN-700-C, constructed by the linker installation using a commercially available chiral molecule, d -camphoric acid, on PCN-700. PCN-700-C exhibits remarkable stability and enantioselectivity in the luminescent sensing of a variety of chiral drugs (Figure S1).

2018年10月15日 · 美国德州农工大学周宏才教授（通讯作者）课题组 在 Chem. Soc. Rev. 上，发表了题为" From Fundamentals to Applications: A Toolbox for Robust and Multifunctional MOF Materials "的综述。 从理论基础到应用的角度，教你构建稳定和多功能化的金属有机框架。 【图文导读】 1.MOFs的设计与合成. 在构建MOFs之前，需要了解的是：MOFs作为一种金属簇与有机配体的结合物，很多组件都会对最终的框架结构产生影响，比如连接物设计、连接物鳌合、结合 …

2019年11月26日 · In this computational study, we show that rational modifications of a previously insulating MOF, PCN-700, can lead to newfound electrical conductivity. In order to secure through-bond charge transport (CT) pathways in the framework, we consider the possibility of introducing electroactive DHBQ linkers via sequential linker installation.

2023年5月9日 · 周宏才团队将这种设计策略进一步引入锆基MOF中，设计了甲基化的4,4'-联苯二甲酸来构建一种名为PCN-700的MOF。 PCN-700含有配位不饱和的锆簇，具备bcu拓扑网络。 这些探索极大地丰富了MOF的结构，赋予了这类功能材料巨大的应用潜力。 稀土元素（RE）和羧酸配体之间多样的配位模式促进了各式各样的多核簇的出现。 然而，在MOF研究的早期阶段，多核稀土簇常常被视为合成上的偶然产物，而大多数已报告的稀土MOFs都是基于单核/双核簇或链状 …

These methods provided plausible alternative ways to solve the issues mentioned above, and involved resorting to a responsive Zr-MOF system, namely PCN-700, as the prototype, assembled using the...

2018年2月9日 · 同时，该团队报道的pcn-700系列，其中bdc-nh 2 可以实现在mof框架内的有序分布，热分解后没有形成介孔。这表明只有连接体缺陷不会导致介孔的形成，而伴随孔道扩展的簇缺陷才是介孔形成的原因。

2023年9月15日 · Zhou et al. [86], [87] reported the synthesis of multivariate MOFs with precisely positioned functional groups via sequential linker installation in a Zr-MOF, namely, PCN-700. The terminal OH–/H 2 O ligands in the framework were eliminated, and liner dicarboxylate linkers with different lengths and functionalities were subsequently installed ...

2024年5月16日 · Luminescent thiazole-decorated metal−organic frameworks are versatile and multifunctional materials for diclofenac sodium detection and removal from wastewater.
