| Outline of Final Research Achievements |
Polycyclic aromatic compounds containing fully unsaturated pentagon ring(s) (CP-PAHs) have been intensively studied because of their unique properties such as high electron affinity and reactivity. In this research project, we demonstrated an efficient route for the synthesis of tetrabenzo-fused pyracylene (TBP), which includes both pyracylene and tetracene moieties as key segments. TBP was shown to possess high electron affinity and was found to undergo addition reactions with n-butyllithium or benzyne. These unique reactions allowed us to create 1,4-addition compound or triptycene-type adduct with a curved or planar π-system, respectively. These compounds exhibited distinct emission behaviors in a concentrated solution and solid state.
