Yaghi 10.1021/ja409033p.s003 https://acs.figshare.com/articles/dataset/Single_Crystal_Structure_of_a_Covalent_Organic_Framework/2359609 The crystal structure of a new covalent organic framework, termed COF-320, is determined by single-crystal 3D electron diffraction using the rotation electron diffraction (RED) method for data collection. The COF crystals are prepared by an imine condensation of tetra-(4-anilyl)­methane and 4,4′-biphenyldialdehyde in 1,4-dioxane at 120 °C to produce a highly porous 9-fold interwoven diamond net. COF-320 exhibits permanent porosity with a Langmuir surface area of 2400 m<sup>2</sup>/g and a methane total uptake of 15.0 wt % (176 cm<sup>3</sup>/cm<sup>3</sup>) at 25 °C and 80 bar. The successful determination of the structure of COF-320 directly from single-crystal samples is an important advance in the development of COF chemistry. 2013-11-06 00:00:00 COF crystals COF chemistry Covalent Organic FrameworkThe crystal structure rotation electron diffraction Langmuir surface area data collection imine condensation 80 bar
