Supramolecular Architecture of Molecular-Level-Ordered 1,1’-Ferrocenedicarboxylic acid with Poly(4-vinylpyridine) for Bulk Magnetic Coupling |
| 초록 |
Molecular-level ordering provides a powerful approach to enhancing the properties of materials. However, the precise arrangement of molecules in a bulk material is a considerable challenge. To overcome such limitations, hydrogen bonding directed self-assembly has drawn a lot of attention due to its facile nature in controlling molecular-level order. In this study we report ordering of the magnetic Fe centers achieved through hydrogen bonding between poly(4-vinylpyridine) (P4VP) and 1,1’-ferrocenedicarboxylic acid (FDA). FDA is uniformly distributed in a ordered polymer matrix, with each Fe center in P4VP-FDA linked at the molecular-level through polymeric bridges in a face-centered cubic structure. The P4VP-FDA in bulk form show a large enhancement of magnetic moment with a paramagnetic resonance and asymmetric current-voltage characteristics similar to the properties of electrode-FDA-electrode architecture. |
