Ladder π‐conjugated compounds, which have fully ring‐fused polycyclic skeletons, are an important class of materials possessing significant potentials for application in organic electronics. The incorporation of main‐group elements, such as B, Si, P, S, and Se, into the ladder skeletons as bridging moieties is a powerful strategy to endow unusual electronic structures as well as suitable molecular arrangements in the solid state, giving rise to attractive photophysical and electronic properties. Recent efforts have produced a number of fascinating ladder materials, some of which indeed showed high performance as light‐emitting materials and charge carrier transporting materials. This Focus Review is an overview of the progress in this chemistry, focusing on several important π‐conjugated skeletons.
