Abstract

Some of the published data in Table 3 of the paper Langmuir 2002 are corrected because contamination of the decamethylferrocene caused an erroneous electrode response, i.e., a shift of the voltammetric peak potentials. Careful re-examination of all systems using decamethylferrocene of highest purity led to the data given in Table 1 of this correction. The new ¢Gõ X-(WfNB) data deviate from the erroneously reported ones especially in the case of the anions valeriate, capronate, and oenanthate. For the other anions listed in Table 1, the deviations are marginal; however, we feel that the correct values must be reported. The technique used provides a standard deviation (n ) 12) of the free energies of 0.16 kJ mol-1. As log(P) values (P is the partition coefficient) are usually used for assessing the liphophilicity of compounds, it is worth mentioning that the new data of ¢Gõ X-(WfNB) give only slightly different new log(P) values. Re-examination of all other data reported in the previous publication proved that they are completely correct. LA0209233 10.1021/la0209233 Published on Web 03/05/2003 Table 1.
