Iodine cyclic voltammetry

The electrochemical behavior of poly(ferrocenylsilanes) has been studied at three levels—in solution by cyclic voltammetry, as films deposited on electrodes, and in the solid state via iodine doping. Solution cyclic voltammetric oxidation and reduction has shown that the polymer, where R/R is Me/Me, reversibly oxidizes in methylene chloride in two stages, apparently with the first oxidation being on alternating iron atoms along the chain.29 Films cast on electrodes behave in a similar way and also show an electrochromic response to oxidation and reduction.30... 

Hall and Polis 7 prepared a series of polyarylamines using an aromatic nucleophilic substitution-reduction sequence (Scheme 4.20). Hence, 2,4-dinitrofluorobenzene 66 was treated with />-diaminobenzene to afford tetranitro 67, which was reduced to give the corresponding first generation, diamine 68. Repetition of this sequence afforded the second generation tetradecaamine 69. These starburst polyarylamines were complexed with iodine to form semiconducting materials and were the first dendrimers to be examined by cyclic voltammetry. 

A new class of highly conducting charge-transfer complexes (306 R=H or Me, X = Cl, Br, or I) has been prepared. ° Cyclic voltammetry of the bis(dithiafulvenyl)-derivatives (307) and (308) has been reported.Oxidation of the bis(dithiolan) (309) with iodine in the presence of aluminium chloride yields the crystalline radical cation salt (310). ...

In the 1980s, Andrieux et al. [83] studied the electrochemical behavior of alkyl halides in DMF using cyclic voltammetry. For Fbutyl iodide, two separate waves were recorded, each one related to the exchange of one electron. The first one was attributed to the reduction of the halide with cleavage of the C-I bond to give a t-butyl radical and an iodine anion. The second one is the reduction of this radical into the t-butyl anion. For sec-butyl iodide, both peaks are very close... 

The synthesis of polyferrocenophanes has been achieved by the radical homo- and co-cyclopolymerization of monomer 48 as shown in Scheme 10." The homopolymerization reaction was also investigated in the presence of cationic initiators only AIBN-initiated reactions yielded high molecular weight polymers. Cyclic voltammetry of the homopolymer 49 showed two oxidation waves at —0.13 and +0.05 V in dichloromethane, while copolymer 50 showed only one oxidation wave at -0.03 V The conductivity of these polymers was also examined. Doping of 49 and 50 with iodine under an argon atmosphere resulted in conductivities of 5.3 X 10 and 1.6 X 10 S/cm, respectively. However, rmder ambient condi-...
