研究の背景 Background


Organic frameworks possessing both “well-designed, structured domains of a functional molecule” and “internal permanent pores” have attracted much attention from viewpoints of porous materials capable of absorbing and separating certain gas or other chemical species selectively and as optoelectronic materials with charge transport ability. Furthermore, host-guest chemistry in the frameworks can provide a new class of functional materials whose properties can be tuned by guest species within the pores. 

研究の目標 Outcome


Highly crystalline organic frameworks possessing both “structured domains of a functional molecule” and “internal permanent pores” have been constructed by our design strategy based on networking through multiple hydrogen bonding. The flexibility of the frameworks is possible to be tuned by topology of the networks. The frameworks can be applied for selective sorption and separation materials of certain gas and other volatile chemical species and for energy storage materials.
