A series of crossconjugated ladder polymers and oligomers (see figure) are synthesized by a one‐step palladium‐catalyzed polycondensation reaction. The polymers are soluble in various organic solvents owing to their nonplanar structure. The structure and physical properties of these compounds are investigated, and indicate that the π‐electrons are mainly localized within anthraquinodimethane units of the structures.
