Analysis of a nanoporous material with a flexible backbone

This material is a nanometer-sized fine porous material with a doubly nested structure. By exchanging ions included in the material, the size of the fine pores can be controlled on a level of one hundredth of a nanometer (one hundred billionth of a meter). Since this crystal is stable and durable, the behaviors of the states immediately after synthesis, dehydration and water readsorption can be measured with high precision by studying a single crystal using Rigaku's SCXmini benchtop diffractometer. These studies show the possibilities that various gases (such as nitrogen, oxygen and CO2) and hazardous materials can be effectively decomposed.
