    • The calixarenes were sketched and optimized by using the esff force field of the Biosym package Insight/Discover (Release 95.0, Biosym/MSI, San Diego, CA, 1995), on an IBM RISC 6K workstation. The standard Discover 3 algorithms were selected with their default inputs (0.001 for BFGS Newton energy convergence). Due to the medium size of the molecules, no cutoff was used to compute the non-bond contribution

    • 2+ is not and may be related to the electronic structure of the complex. Curiously also, no d-d transition was observed (at least below 1 000 nm) for the phenol adduct which was EPR silent at 120 K. Its EPR signal was observable only below 30 K. Such a behaviour is very unsusual. For a previous related example, see

    • In the case of the other phenol derivatives, a very fast decrease to 0 of the electrolytic current indicates a passivation of the electrode. This might be the result of a polymerisation on the electrode either by catalytic oxidation or by direct oxidation of these phenols. Their oxidation potential are lower than that of the pFPhOH
