Far fewer n‐type polymer materials (low‐lying LUMO and HOMO; electron acceptors) than p‐type polymer materials (high‐lying LUMO and HOMO; electron donors) have been reported to date. In their Communication on page 3648 ff., J. Liu and co‐workers describe a strategy for the transformation of conjugated polymers from electron donors to electron acceptors. Their approach involves replacement of a CC unit by a B←N unit to lower both the LUMO and HOMO by approximately 0.6 eV.
