for advancing the field of semiconducting polymers is to create new π‐conjugated systems as building units. This work reports on a series of electron‐deficient hybrid naphthalene‐based π‐conjugated systems in which two different units among benzoxadiazole, benzothiadiazole, benzoselenadiazole, and benzopyrazine (quinoxaline) were fused. These π‐conjugated systems were synthesized in excellent yields
