Preparation of Complex Ratio‐Dependent Nanomaterials from Polymerizable Hydrogen‐Bonded Liquid Crystal

摘要

Abstract A scalable approach to generating different nanomaterials from the same hydrogen‐bondeded complex by photo‐crosslinking is described. The hydrogen‐bonded complex exhibits a smectic or columnar mesophase, depending on the molar ratio between the donor and acceptor. The mesophase structure is effectively retained after photo‐crosslinking. Polymer nanosheets with negatively charged carboxylate groups can be prepared from the complex with the smectic mesophase after subsequent extraction and chemical treatment, and they show effective adsorption of Pd2+. Meanwhile, a nanoporous polymer is successfully achieved from the complex having the columnar mesophase by using the same technology of photo‐crosslinking and solvent treatment. This work provides a new strategy to fabricate different nanomaterials from the same hydrogen‐bonded complex system.
