Synthetic strategies that enable rapid construction of covalent organic nanotubes with an angstrom-scale tubular pore remain scarcely reported. In this research article, we report a remarkably simple and mild one-pot polymerization protocol, employing POCl 3 as the polymerization agent. This protocol efficiently generates polypyridine amide foldamer-based covalent organic nanotubes of 2.8 nm long at yield of 50%. Trapping single file water chains in their 2.8 Å tubular cavity rich in H-bond donors and acceptors, these tubular polypyridine ensembles
