Molecular organic solids for gas adsorption and solid-gas interaction

Abstract

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] This following dissertation comprises three closely related sets of studies in order to explore the potential of molecular organic solids as a new type of microporous materials for gas storage. Section I will briefly discuss the currently active research area of microporous materials for gas storage and separation. These materials can be structurally well ordered with well-defined pore sizes, or they can be structurally disordered with a wide variety of different pore sizes. Section II will describe the synthesis and crystal engineering of several molecular organic compounds for gas storage and separation. These molecular materials are crystalline and can be further classified as porous organic crystals, nonporous organic crystals and frustrated organic solids according to their structural features. Section III will discuss amorphous molecular organic solids as a new member of porous materials family that has been largely neglected in the past two decades. These materials are composed of small organic molecules that usually have large inner cavities within the skeleton of molecular structures. Section IV will describe the significant gas-induced phase change of host frameworks of several organic crystals.
