摘要：

(Figure Presented) Twelve of one, a dozen of the other: Synthetic pseudometallic molecules were prepared by fully substituting the [B 12H12]2_ ion with 12 alkoxy groups. Reversible redox reactions reveal substituent-dependent potentials varying over 1.2 V (see picture) which were characterized and correlated using Hammett and QSAR linear free-energy relationships. © 2007 Wiley-VCH Verlag GmbH & Co.
