After performing a detailed inspection of these organic semiconductors, we arrive at the conclusion that the construction of a two-dimensional (2D) electronic structure with large orbital overlaps in the solid state is the key. This can be realized by tuning these molecular factors; for example, the use of linearly pi-extended systems with fused aromatic ring structures, heteroatom incorporation, and the use of suitable substituents for 2D packing, such-as herringbone or 2D bricklayer packing.
