Abstract
The redox properties of 23 alternant PAH and non-alternant mono- and bis-CP-PAH that contain annelated peripheral pentagons were determined using cyclic voltammetry. The results show that peripheral cyclopenta-fusion markedly enhances their electron affinity. Unexpectedly for the non-alternant PAH, a good linear correlation between the first reduction potential [E1/2(0/−1) V vs.
