Left‐handed helical polymer resin nanotubes prepared by using N‐palmitoyl glucosamine

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.
