Isomerism Effect on Flexibility of Layered Frameworks in Organic Salts of 4,4′-Biphenyldisulfonic Acid with Primary Amines

Organic salt of 4,4′-biphenyldisulfonic acid with isopropylamine yields a flexible layered framework with guest-responsive channels, while the salt with n-propylamine does a rigid one with fixed channels. The flexibilities of the framework are modulated by an isomerism effect of alkyl groups on the...

Zusammenfassung:Organic salt of 4,4′-biphenyldisulfonic acid with isopropylamine yields a flexible layered framework with guest-responsive channels, while the salt with n-propylamine does a rigid one with fixed channels. The flexibilities of the framework are modulated by an isomerism effect of alkyl groups on the basis of different directions of methyl groups.
