Microporous structures having phenylene fin: Significance of substituent groups for rotational linkers in coordination polymers

• Microporous coordination polymers having various shaped apertures were synthesized.
• Porous structures are precisely characterized crystallographically.
• The substituents exert a notable influence on the pore depending on phenylene units.

Microporous coordination polymers having various shaped apertures were synthesized and crystallographically characterized using substituted terephthalate ligands. The substituents exert a notable influence on the channel size and shape depending on the orientations and disordering of the phenylene units such as a fin. This is a new aspect of porous coordination polymers, which would provide important information for a precise design of the micropore.
