Extended π system: A nickel(0)-mediated reaction afforded dinaphthopentalene derivatives, whose electronic and electrochemical properties depend on the fusion patterns. Very high hole mobility was observed for an amorphous material, and the compounds are applicable to organic heterojunction photovoltaic cells (see picture).
