High molecular mass, uniform structure, and complete solubility characterize the novel ladder polymers 1 . The formation of dication 2 from a model analogue of 1 by oxidation with 2,3‐dichloro‐5,6‐dicyanobenzoquinone (DDQ) and subsequent dehydration with trifluoromethanesulfonic acid reveals that 1 is a potent precursor for the preparation of heteroanalogous, ionic poly[ n ]acenes. R 1 = p ‐C 6 H 4 ‐ n ‐C 10 H 21 , R 2 = p ‐C 6 H 4 rBu; counterion CF 3 SO 3 − .
