Outline of Final Research Achievements

We measured and analyzed infrared absorption spectra of a radical cation (monomer), its dimer, and a dication of oligothiophene derivatives. Some vibrational modes which induce intermolecular charge transfer are identified. Radical anions (RA) of triphenylene (planar) and sumanenetrione (bowl-shaped), were also studied by infrared absorption spectroscopy. By comparing infrared absorption spectra measured under inert gas atmosphere and those obtained by quantum chemical calculations, we found that the threefold axis in triphenylene RA disappears while the axis in sumanentrion RA remains.
We studied photoexcitation dynamics of regioregular poly(3-hexylthiophene) in a spin-coated film and in solutions by femtosecond time-resolved infrared spectroscopy. We also studied the molecular structures and their dynamics of photoexcited states of fast photochromic molecules and a flapping molecule by time-resolved infrared spectroscopy.
