Abstract Details

2010, Master of Science, Miami University, Physics.
Metal-Organic Frameworks (MOFs) are a new class of materials notable for a remarkable range of structural conformations, high porosity and acceptance of mobile charged guest species, or counter-ions, within their network of molecular channels. If the counter-ions were highly mobile, the metal-organic framework would represent a new class of superionic conductor. Presented in this study is an attempt to characterize the ionic properties of two particular metal-organic frameworks. The zero-frequency conductance of the samples is found to be minimal, suggesting that the materials studied are not ionic conductors. The ions in each of the MOFs studied exhibit multiple glass transitions. The particular frequency-temperature scaling associated glassy dynamics was observed in the dielectric response.
