| Outline of Final Research Achievements |
Mechanisms of gate phenomena, which elastic layer-structured MOFs (ELMs) show on gas sorption, were examined by measuring spectroscopic methods such as electron spin resonance, spin-lattice relaxation in 1H-NMR, and IR absorption for ELM-11 ([Cu(bypiridine)2(BF4)2]) which shows a marked gate phenomenon on CO2 sorption. The mechanism was suggested for the gate phenomenon from the results obtained by the spectroscopic methods: the gas adsorption on the external surface influences on the structure of ELM-11 and triggers the expansion of interlayer distance.
Amine-modified graphite oxides (AGOs) were prepared as a new material showing a gate phenomenon, and examined by XRD, gas sorption, IR, TG measurements. A type of AGO was found to show a gate phenomenon on gas sorption for a mixed vapor of water and CO2, accompanied by an expansion of the interlayer distance.
