| Outline of Final Research Achievements |
Photochemical conversion of small aromatic chromophores, e.g. benzene, naphthalene, phenanthrene, etc., into polycyclic frameworks have been investigated.
(1) For the photoreaction of azacyclophanes incorporating two benzene chromophores, benzene photodimerization took place to afford various polycyclic skeletons. Depending on the substituents on the benzene rings, we have observed formation of p,p'-dibenzene, octahedrane, and cage diene benzene dimers. Relative energies of the benzene dimer were evaluated by theoretical calculation to have insight into the substituent effects.
(2) Diarylethenes, incorporating benzene, naphthalene, or phenanthrene chromophores, were converted into polycyclic aromatic frameworks, namely phenacenes in which the benzene rings were fused in a zigzag array. By applying a continuous flow photoreaction technique, various phenacenes were successfully synthesized with high chemical yield.
