Electroactive Polymerization Behaviors of Fused-Pentagon Chlorofullerenes: #1809C60Cl8 and #271C50Cl10

The fullerenes that violate isolated pentagon rule (IPR) have unusual electronic properties resulting from their fused-pentagon structures. Numerous non-IPR fullerenes have now been captured by chlorination, affording opportunity to go insight into the properties involved in non-IPR fullerenes in the forms of chlorofullerenes (CFs). Here cyclic voltammetry (CV) is employed to probe the electrochemical properties of non-IPR #1809 C 60 Cl 8 in comparison with those of #271 C 50 Cl 10 . Differing from IPR-satisfying CFs such as C 60 Cl 8 and C 60 Cl 10 (referring to I h -symmetric C 60 ), the two non-IPR CFs exhibit divergent electroactive polymerization characters. In addition, the electrocatalytic effect of ferrocene that is otherwise employed as internal reference has been shown in the CV process of CFs.
