Although the preparation of single‐handed helical inorganic and hybrid organic‐inorganic nanotubes is well developed, approaches to the formation of single‐handed organopolymeric nanotubes are limited. Here, left‐handed helical m ‐phenylenediamine‐formaldehyde resin and 3‐aminophenol‐formaldehyde resin nanotubes were prepared by using N ‐palmitoyl glucosamine that can self‐assemble into left‐handed twisted nanoribbons in a mixture of methanol and water. In the reaction mixture, the helical pitch of the nanoribbons decreased with increasing reaction time. The resin nanotubes were obtained after removing the N ‐palmitoyl glucosamine template, and circular dichroism spectroscopy indicated that the organopolymeric nanotubes had optical activity. Carbonaceous nanotubes were then prepared by carbonization of the 3‐aminophenol‐formaldehyde resin nanotubes.
