Metal-Organic Frameworks and Porous Coordination Polymers: Properties and Applications

摘要

In this review, properties and applications of metal-organic frameworks (MOFs) and porous coordination polymers (PCPs) are described. Many MOFs and PCPs are highly flexible and responsive to external stimuli. Sometimes they transform their structures to others by maintaining the single crystallinity. For decades, MOFs and PCPs have been regarded as a class of the promising materials for hydrogen storage and carbon dioxide capture applications since they adsorb large amounts of gases at low temperatures. However, their gas uptake capacities decrease dramatically at ambient temperature compared to those at low temperatures because they physic-sorb gases by weak interaction energies. Therefore, to enhance gas storage and separation abilities of MOFs and PCPs at ambient temperature, we have modified their pore spaces. In this review, some characteristic properties of MOFs and PCPs will be introduced, and various strategies for modifying the pore spaces of PCPs and MOFs for hydrogen storage and carbon dioxide capture will be presented.
