Outline of Final Research Achievements |
One-dimensional supramolecular columnar phases composed of porphyrins (electron donor: D) and benzo[ghi]perylenetriimides (electron acceptor: A) through triple hydrogen bonds have been successfully constructed to perform sequential light-harvesting and electron-transfer processes. A series of benzo[ghi]peryleneimide derivatives have been synthesized to examine the substituent effects such as imide and nitrile groups on the spectroscopic and electrochemical properties. The introduction of substituents onto the benzo[ghi]perylene (Bp) ring successfully enabled control of spectroscopic and electrochemical properties as compared to the non-substituted reference Bp. Then, formation of the 1 : 1 supramolecular complex between zinc porphyrin and benzo[ghi]perylenetriimide derivatives through triple hydrogen bonds was confirmed by Job’s plot of 1H NMR titration. Then, the one-dimensional supramolecular nanoarrays were successfully prepared in a mixed solvent.
