Outline of Final Research Achievements

Organic synthesis of fused aromatic compounds of a large number of the benzene ring requires multistep synthetic procedures whereas photocyclization process of corresponding ethene precursors is a facile procedure for synthesizing them. In advance of the main study, we made a flowphotoreactor that achieves efficient photocyclization. By using this instrument, we synthesized small phenacene derivatives, such as phenanthrene, chrysene and picene, with the bromomethyl and formyl groups at various substituted positions used as the basic chromophores for the following photocyclization of diarylethenes. We prepared various diarylethenes, and carried out their photocyclization to obtain a variety of cyclized aromatic compound. Photophysical properties of compounds were studied based on emission and transient absorption measurements as well as the single crystal structures by X-ray crystallography. The electronic properties as semiconductor and electroluminescence devices were examined.
