Outline of Final Research Achievements

It is known that anthracene and its derivatives are widely used as building blocks for opto-electronics materials. Rigid and planar π-conjugated anthracene macrocycles, which would possess latent functionality, have been unprecedented. Based on 2,7-diborylanthracene, which we previously developed, we succeeded in the synthesis of a π-conjugated macrocyclic trimer with rigid and planar conformation composed of 2,7-anthrylene-ethynylene-1,3-phenylene-ethynylene unit. We found that this anthracene macrocycle is π-stacked in solution and forms self-assembled π-stacked nanofibers in the drop cast film.
