Ferrocenyl fulleropyrrolidines: a cyclic voltammetry study

Abstract

The cyclic voltammetry of some fullerene-ferrocene derivatives shows that these compounds possess very interesting electrochemical properties.

Rates and energetics of intramolecular electron transfer processes in conjugated metallofullerenes

“…In the reductive range, the presence of four reductions resemble those seen for the C 60 reference at −1.06, −1.41, −2.07 and −2.36 V [36][37][38][39]. In La@C 82 -exTTF, the oxidative range is dominated by the oxidation of La@C 82 at −0.04 V [40] and the two-electron oxidation of exTTF at +0.05 V. Theoretical calculations corroborate the fact that the singly occupied molecular orbital is localized on La@C 82 rather than on exTTF.…”

Organofullerene Materials

“…However, data for the formation of ferrocenefullerene hybrids are not abundant. Some such dyads have already been synthesized following the methodology of 1,3-dipolar cycloaddition of the appropriate azomethine ylides to C 60 ,with either variable-spacing building blocks or a rigid-bridge alls-bonded framework, in order to tune the redox properties of the system [40,234,[248][249][250][251].Another novel dyad that contained two covalently bound ferrocene units was recently synthesized via cyclopropanation of the fullerene core [252].…”

N-Arylation of Pyrrolidino[3′,4′:1,2][60]fullerene: Synthesis under Solvent-Free Conditions and Electrochemistry of New C60–Acceptor Dyads

“…The new compounds were to a through-space orbital interaction phenomenon called electrochemically characterised by cyclic voltammetry "peri conjugation" [7] or to inductive effects. [6] measurements, and semiempirical PM3 [13] calculations were In recent years, the 1,3-dipolar cycloaddition of azomeperformed to determine the geometry and the HOMOϪ thine ylides to C 60 [8] has been used extensively to prepare LUMO levels of these molecules. fullerene derivatives, [9] and among the different methods available to generate the reactive intermediates, the most successful approach has been the decarboxylation of immonium salts derived from condensation of α-amino acids Results and Discussion with aldehydes.…”
