Dynamic Studies Of Guest Molecules In Metal-Organic Frameworks Using Solid-State Nmr, Yuanjun Lu

Electronic Thesis and Dissertation Repository

Metal-organic frameworks (MOFs) are a new class of porous materials that possess large three-dimensional voids in their structures. In this work, Solid-state NMR (SSNMR) is used to examine the dynamics of guest molecules at various temperatures in MOFs that possess different types of channels. Chapter 2 introduces the ¹³CO₂ adsorption behavior in α-Mg formate studied by ¹³C SSNMR in conjunction with molecular dynamic simulation. ¹H-¹³C cross polarization technique has successfully determined the adsorption sites of CO₂ in this type of MOF to be hydrogen atoms. The dynamic analysis detects that at low temperature, …
