Self-assembly of various molecules has been studied to fabricate functional nanostructured materials. Artificial self-assembly provides a “bottom-up” approach to fabricating precise and complex nanostructures. For understanding the change of molecular structure to the assembled structure, Fmoc-AA-gelator was modified with incorporating a hydrazide group, which easily reacts with the aldehyde to make hydrazone. The resulting hydrazone compound was regulated the molecules’ symmetry (C2, C3) and their assembly was observed by SEM images and CD spectra. The intermolecular interactions in the fibril-like assembled structure were composed of π-π interactions between the Fmoc group and core benzene, and hydrogen bonding between acyl hydrazone and amide bonds. It is believed that controlling the molecular structure of one species using hydrazone linkage is easily incorporated functional groups to gelator with functional motif such as stimuli-responsiveness. |
