The formamidoxime configurational Z isomer coupled with the pyridylbiscarboxamide conformational codon were used to fold planar, curved structures. When embedded into macrocycles, this folded motif promotes dimerization through π–π stacking and hydrogen-bonding and the formation of tubules akin to molecular channels in the solid state.
甲脒肟构象 Z 异构体与吡啶基二甲酰胺构象密码子被用于折叠平面弯曲结构。当嵌入大环时,这种折叠图案可通过π-π堆叠和氢键作用促进二聚化,并形成类似于固态分子通道的管状结构。

The partial positive charge of amide protons is used to promote macrocyclization and form crown-ether analogs. Their deprotonation generates very selective pH-switchable alkaline earth ion receptors only in the presence of an appropriate substrate.
