Towards high CO2 capacity: Introduction of amine-containing linkers to HTFG-COF by pre- and post-synthetic methods — •Kerstin Gottschling1,2, Linus Stegbauer1,2, and Bettina V. Lotsch1,2 — 1Max-Planck-Institut für Festkörperforschung — 2Ludwig-Maximilians-Universität München
The development of materials that are suitable for the capture, storage and separation of carbon dioxide is an important goal of current research. In this regard, covalent organic frameworks, so-called COFs, stand out as they are light-weight, do not contain problematic elements such as heavy and toxic metals and often show high porosities and gas capacities. The tailoring of HTFG-COF, a hydrazone-based system, towards higher CO2 capacities by the introduction of amine-containing linkers, was investigated. A linker containing terminal tertiary amines was introduced to HTFG-COF by pre- as well as post-synthetic methods. The resulting systems were fully characterized by solid-state NMR spectroscopy, FT-IR, X-ray diffraction and sorption analysis. A significant change of the gas adsorption properties was found and a functionalization grade of 4% for pre- and 8% for post-synthetically modified systems was derived.
