An effective method is reported to synthesize aromatic helical polymer nanochannels by combining both the well‐studied aromatic amide helical codons with pyridine‐oxadiazole helical codons into helical structure sequences. With this strategy, a type of helical polymer nanochannel that shows structure‐directed transmembrane transport functions is synthesized. Although such nanochannels show relatively weak selectivity for the transportation of alkali metal ions, accessible chemical mutation of helical structure sequences will provide a great chance for the design of desired channel property. The straightforward preparation of well‐established pyridine‐oxadiazole helical structure will significantly promote the synthesis of this kind of aromatic helical polymer nanochannels. With the development of aromatic amide foldamers, moreover, a number of “monomers” will be available for the preparation of helical polymer nanochannels.
