Temperature Programmed Infrared and Mass Spectrometry Analysis of Interactions of Covalent Organic Frameworks with Simple Polar and Nonpolar Organic Molecules

Abstract

Thermal analysis of molecule-material interactions is critical for many applications. Temperature programmed studies performed using mass spectrometry and infrared spectroscopy under ultra-high vacuum provide information about these interactions as a function of temperature. Our interest focuses on Covalent Organic Frameworks (COF)s, 3 dimensional porous materials whose building blocks are organic molecules coupled via strong covalent bonds, for sorption and catalytic applications. By studying the interactions of COFs (DC-3, DC-4) with industrial analytes (CO2) and simple polar and non-polar laboratory chemicals (acetone, heptane) the basic principles for more complex systems are revealed.
