TITLE:

"Amorphization and glass formation of metal-organic frameworks"

ABSTRACT:

Metal-organic frameworks (MOFs) have been extensively studied due to their large porosities and flexible chemical compositions, due to their potential applications in such fields as gas and liquid absorption, gas separation, catalysis, sensoring and detection, food storage etc. Amorphization and glass formation of MOFs with disordered structure induced by temperature, pressure, and ball-milling were discovered recently. This MOF glass with hybrid structural units chemically differs from the inorganic, organic and metallic glasses, making it a new family of glassy materials.

This cutting-edge research connects the scientific fields of materials chemistry including materials design for new structures and functionalities, and glassy physics regarding the applicability of the condensed matter theories. Due to the lack of study on MOF glasses, a great range of topics, such as glass-forming mechanisms, chemical potentials, and the relationships between structures and properties, need to be investigated.

In this thesis, the following aspects of the research with regard to amorphization and glass-forming MOFs are facilitated and developed: (1) Probing crystalline MOF synthesis conditions influence on MOF amorphization; (2) Understanding the physical properties of amorphous MOFs through glass transition and phase transformation; (3) Exploring and promoting the practical applications of MOF glasses.
