    A series of ladder-type multifused arenes (hexacyclic, heptacyclic and nonacyclic units) and the synthesizing methods thereof are provided. The ladder-type multifused arenes are copolymerized with various electron-deficient acceptor units to afford various p-type low-band gap conjugated copolymers.

    A synthesis method of a heterocyclic compound is disclosed. The synthesis method includes steps of: carrying out a McMurry coupling reaction on a first compound having a carbonyl group to form a second compound, wherein the second compound includes an alkyl group which is symmetrical to a symmetrical center, and carrying out a 6π-cyclization on the second compound to form a third compound.
