Solvent-dependent Modification in Morphologies of Molecular Assemblies |
| 초록 |
Fabrication of organic fluorescent nanostructures with different morphologies can give the new insights into the intermolecular interactions with the environment, therefore grant excellent practical applications. To study the morphology of molecular assemblies depending on the solvent environments, 3t-BuAz was prepared from the precursor 3BrAz (1). The terminal t-butyl group seems to allow good solubility in organic solvents of differing polarity. Formation of self-assembled nano/microstructures were initiated by gradual addition of poor solvents to the solutions of 3t-BuAz in good solvents. Grain-like aggregates were readily formed from the tetrahydrofuran and water mixture, whereas long fibrous structures were observed from dichloromethane and methanol mixture. The morphology in nano/microstructures induced by different solvent environments were characterized by SEM, OM, FOM and XRD observations. Light-responsive properties of the molecular assemblies have been also investigated. |
