Electrochemical Reduction of Oligo-nitrocalix[4]Arenes - Molecules with Multiple Redox Centers, Different Conformations and Variable Shape
2015
Abstrakt
Calix[4]arenes substituted by one, two, three or four nitro groups enable electrochemical investigation. As molecules with multiple redox centers, they attract attention namely from the fundamental point of view: dealing with the question of reduction pattern, mutual electron interaction within the molecule, order of electron transfer steps, possible radical nature of intermediates etc.
Besides that, this contribution has an additional message - use of electrochemical experimental data for acquiring information on 3D-shape of dissolved molecule in solution, on its conformation, substitution site and dynamic behavior influenced by conformation and positions of substituents.
