Yang, Chongqing;Jiang, Kaiyue;Zheng, Qi;Li, Xinle;Mao, Haiyan;Zhong, Wenkai;Chen, Cheng;Sun, Bing;Zheng, Haimei;Zhuang, Xiaodong;Reimer, Jeffrey A.;Liu, Yi;Zhang, Jian research published 《 Chemically stable polyarylether-based metallophthalocyanine frameworks with high carrier mobilities for capacitive energy storage》, the research content is summarized as follows. Covalent organic frameworks (COFs) with efficient charge transport and exceptional chem. stability are emerging as an import class of semiconducting materials for opto-/electronic devices and energy-related applications. However, the limited synthetic chem. to access such materials and the lack of mechanistic understanding of carrier mobility greatly hinder their practical applications. Herein, we report the synthesis of three chem. stable polyarylether-based metallophthalocyanine COFs (PAE-PcM, M = Cu, Ni, and Co) and facile in situ growth of their thin films on various substrates (i.e., SiO2/Si, ITO, quartz) under solvothermal conditions. We show that PAE-PcM COFs thin films with van der Waals layered structures exhibit p-type semiconducting properties with the intrinsic mobility up to ~19.4 cm2 V-1 s-1 and 4 orders of magnitude of increase in conductivity for PAE-PcCu film (0.2 S m-1) after iodine doping. D. functional theory calculations reveal that the carrier transport in the framework is anisotropic, with the out-of-plane hole transport along columnar stacked phthalocyanine more favorable. Furthermore, PAE-PcCo shows the redox behavior maximumly contributes ~88.5% of its capacitance performance, giving rise to a high surface area normalized capacitance of ~19 μF cm-2. Overall, this work not only offers fundamental understandings of electronic properties of polyarylether-based 2D COFs but also paves the way for their energy-related applications.
