Outline of Final Research Achievements

Porous materials composed of acetylenes, highly-unsaturated sterically-narrow chemical species, are expected to absorb hydrogen gas molecules physically and chemically. In this study, we aimed construction of such materials based on pi-conjugated macrocyclic molecules so-called dehydrobenzoannulene (DBA), possessing acetylene moieties preorganized with well-defined geometry. First, we elucidate quantitative intermolecular interactions between the DBA and gas molecules. Subsequently, we successfully constructed porous materials, in which DBA molecules are networked via coordination bonds or hydrogen bonds to form nano-meter pores surrounded by DBA. Some of them show good gas absorption property.
