Unequal brothers: Benzoperylene carboxylic acid derivatives with flexible chains not only form charge‐transporting columnar liquid crystals (see graphic), their charge‐transport properties can also be tuned to be either of n ‐ or of p ‐type: relatively minor changes in the substitution pattern yield different materials that are complementary enough to form red‐fluorescent charge‐transfer complexes and p – n junction electronic devices.
