Supramolecular nanochannels self-assembled by helical pyridine–pyridazine oligomers†
Abstract
Herein, we demonstrate a supramolecular nanochannel formed by intermolecular π stacking of pyridine–pyridazine helical oligomers, wherein alkali ions could be easily recognized and transported. Importantly, this nanochannel also revealed reversible collection and triggered-release behaviors via modulating the folded and unfolded states of helical pyridine–pyridazine oligomers.
