Abstract
Constructing three dimensional (3D) covalent organic frameworks (COFs) through the entanglement of two dimensional (2D) nets is a promising but underdeveloped strategy. Herein, we report the design and synthesis of a fluorine functionalized 3D COF (3D-An-COF-F) formed by entangled 2D sql nets. The structure of 3D-An-COF-F was determined by the combination of continuous rotation electron diffraction technique and modelling based on the chemical information from real space. Interestingly, compared to the isostructural 3D-An-COF without F atoms, 3D-An-COF-F showed an improved CO2 sorption ability and higher CO2/N2 selectivity. Our study not only demonstrated the generality of constructing 3D COFs with entangled 2D nets by introducing bulky groups vertically in planar building blocks, but also will expand the diversity of 3D COFs for various applications.
期刊介绍：
Chinese Journal of Polymer Science (CJPS) is a monthly journal published in English and sponsored by the Chinese Chemical Society and the Institute of Chemistry, Chinese Academy of Sciences. CJPS is edited by a distinguished Editorial Board headed by Professor Qi-Feng Zhou and supported by an International Advisory Board in which many famous active polymer scientists all over the world are included. The journal was first published in 1983 under the title Polymer Communications and has the current name since 1985.
CJPS is a peer-reviewed journal dedicated to the timely publication of original research ideas and results in the field of polymer science. The issues may carry regular papers, rapid communications and notes as well as feature articles. As a leading polymer journal in China published in English, CJPS reflects the new achievements obtained in various laboratories of China, CJPS also includes papers submitted by scientists of different countries and regions outside of China, reflecting the international nature of the journal.
