Outline of Final Research Achievements

We have established the synthetic method for hetero-aromatic ring-introduced indanedione monomers and their dimers, such as 4-pyridyl, 2-pyradyl, 2-thienyl, 3-methyl-2-thienyl groups derivatives. In their crystal structures, the dissociative central C-C bond moieties were successfully aligned in a parallel manner. In addition, we confirmed C-C bond dissociation/re-association by heating/cooling in 4-pyridyl derivative. Furthermore, unexpectedly obtained porous structure in 4-pyridyl derivative showed high stability against heat and enabled us to reveal its crystal structure change induced by the removal of the solvents from the pores. This results may connect to the new project to investigate indandione dimers-based molecular networks as the molecular recognition/adsorption fields.
