Singlet fission has emerged as a promising strategy to avoid the loss of extra energy through thermalization in solar cells. A family of dimers consisting of nitrogen‐doped pyrene‐fused acenes that undergo singlet fission with triplet quantum yields as high as 125 % are presented. They provide new perspectives for nitrogenated polycyclic aromatic hydrocarbons and for the design of new materials for singlet fission., Come Together: By introducing dibenzodiazahexacene moieties in a dimeric architecture, a new type of singlet fission material was obtained. Solvent‐dependent triplet quantum yields of up to 125 % were achieved.
