| Outline of Final Research Achievements |
We synthesized new high dimensional and X-shaped conjugated compounds to obtain high functional and photoluminescent organic materials. 9,9’-Bianthracene compounds with four diphenylaminophenyl or diphenylmethanol groups into the peripheral moieties were synthesized and they could be used as photoluminescent materials capable of optical resolution. X-type conjugated compounds modifying the 1,3,6,8-positions of phenanthrene were useful as blue light-emitting materials. Phospha[7]helicenes with large conjugated parts were synthesized. We investigated photo-physical properties of phthalimide compounds with oligoselenophene units. They are useful for the application to light-sensitive semiconductors.
