The relationship between electronic structure and chemical stability is discussed for three different classes of low band‐gap oligomers and polymers. In oligo‐ and poly[n]acenes as well as in poly‐(arylenemethide)s, the low band‐gap character is connected with a high chemical reactivity due to an energetically favored rearomatization of olefinic or quinonoid substructures, respectively. For double‐stranded oligo‐ and poly(rylene)s, the stability is dramatically increased. Therefore, rylenes appear especially promising in the field of low band‐gap materials.
