Abstract
Conjugated hydrocarbons with polycyclic frameworks have attracted much attention because of their utility in organic electronic devices. Although dibenzopentalenes possess a 4nπ-electron system, they are fairly stable compounds with a planar structure. Thus, appropriate modification would provide them with desirable electronic properties. Recently, we have developed a novel reaction yielding dibenzopentalene derivatives from readily available o-bromoethynylbenzenes using commercially available nickel complexes. The method is accessible to π-extended pentalene derivatives bearing various functional groups and aromatic ring systems. Among them, a dinaphthylpentalene derivative showed a very high hole mobility as amorphous materials. Furthermore, it was employed as a p-type material for organic heterojunction photovoltaic cells. The results indicate that π-extended pentalenes would serve as a good platform for materials applicable to organic electronics.
