| Outline of Final Research Achievements |
In order to develop the chemistry of diazaporphyrins that have high electron-accepting and light-harvesting properties, we have (i) synthesized new diazaporphyrin derivatives bearing various substituents at the periphery, (ii) disclosed their structure-property relationships, and (iii) applied some derivatives in organic solar cells. As a result, we have found that the amino-substituted donor-acceptor-type diazaporphyrins show the intramolecular charge-transfer character derived from the intrinsically electron-withdrawing nature of the diazaporphyrin. Furthermore, we have succeeded in fabricating dye-sensitized solar cells using some diazaporphyrin-based dyes and revealed their potential as the photofunctional materials.
