| Outline of Final Research Achievements |
This work demonstrated that crystal downsizing of two-dimensional flexible coordination polymers incorporating cyanido-bridged structures impacted on the thermal expansion behavior and water adsorption isotherms by comparing them with those of bulk particles. The nanoparticles exhibited a smaller coefficient of thermal expansion than the bulk particles. Moreover, structural changes in the nanoparticles due to water adsorption occurred in the lower pressure region than the bulk. Interestingly, it was found that the amount of water accommodation by the nanoparticles increased by one molecule than the bulk. These characteristics were caused by structural changes via crystal downsizing, where the zigzag layers had the corresponding contracted structures.
