| Outline of Final Research Achievements |
In this research project, we aimed to create new core-modified azaporphyrins that absorb visible-near infrared (NIR) light for application to organic solar cells. First, we established a general method for introducing π-conjugative substituents onto the peripheral carbons of diazaporphyrins. We investigated the optical and electrochemical properties of the newly prepared diazaporphyrins. The introduction of an electron-donating substituent to the peripheral carbon causes a large enhancement of the visible-light harvesting ability of the diazaporphyrin π-system. Second, we synthesized novel dipyrrin-boron and azadipyrrin-boron complexes bearing π-conjugative substituents on the pyrrole rings. We have revealed that the aza-substitution of π-extended dipyrrin-boron complexes is an efficient method for enhancing the NIR light-harvesting ability.
