Abstract
We have recently introduced "inherently chiral" enantiopure electrode surfaces of outstanding chirality manifestations, including large potential differences for the enantiomers of chiral probes in voltammetry experiments. [1-5] They can be prepared by electrooligomerization from monomer 1, having an atropoisomeric dibenzothiophene core, and consist of a mixture of macrocyclic and open-chain oligomers as those represented in the Figure, which we have electrochemically investigated one by one in detail. The results will be presented and discussed. Especially the macrocycles provide a quite attractive casebook of interactions between equivalent redox centers, possibly also requiring to take into account interactions between facing chains, especially in the case of the smaller ringlet.File | Dimensione | Formato | |
