Step by step : The cluster [3,3′‐Co(1,2‐C 2 B 9 H 11 ) 2 ] − is an excellent platform for making a stepwise tunable redox potential system by dehydroiodination. With the addition of up to eight iodine substituents (purple; see picture), there is a fall in the E 1/2 (Co III /Co II ) value from −1.80 V to −0.68 V (vs. Fc + /Fc; Fc=ferrocene). A practical application of this tunability has been observed in the growth of polypyrrole.
