| Outline of Final Research Achievements |
1,1'-Bi(2-pyridylazulene), in which pyridyl moieties were coupled to a biazulenyl framework for hydrogen bonding between the two azulenyl skeletons. The longest wavelength absorption band of this compound underwent a blue shift or red shift depending on the amount of trifluoroacetic acid added. In addition, single crystals of the mono-protonated species were successfully obtained as the tetrafluoroborate salt. The X-ray diffraction analysis of the salt revealed an intramolecular hydrogen bond between the two pyridyl moieties, giving a racemic mixture of axial chiral species.
