Outline of Final Research Achievements

Polycyclic aromatic hydrocarbons (PAHs) are useful as semiconductor and luminescent materials, and have been actively studied in recent years for their application to organic electronics materials. In the present study, we took advantage of the properties of pyrene, which has a high fluorescence quantum yield, to develop macrocyclic molecules with efficient pi-expansion. The cyclic trimer was successfully isolated and characterized, and a red-shift in the absorption spectrum due to π-expansion was confirmed. In addition, the unique properties of each ring size were clarified.
