Two new high‐performance DPP‐containing donor molecules employing a molecular architecture with three DPP chromorphores ( tri ‐DPP) in conjugated backbones are synthesized and characterized. The two tri ‐DPP molecules with only a structural difference on alkyl substitutions, when blended with PC 71 BM, lead to power conversion efficiencies up to 4.8 and 5.5%, respectively.
