A process for preparing a heteroaromatic compound having a heteroaromatic nucleus substituted with one or more ether groups comprising the step of: condensing at least one hydroxy-group of a compound having said heteroaromatic nucleus, said at least one hydroxy group (—OH) being substituted at &agr;- or &bgr;-positions with respect to a heteroatom of said heteroaromatic nucleus, with an alcohol containing one or more primary or secondary alcohol groups, optionally substituted with nitro, amide, ester, halogen, cyano or (hetero)aromatic groups, using the redox couple of a triaryl- or trialkylphosphine and an azodioxo-compound at a temperature between −40° C. and 160° C.

the first and second oxidation potentials (ΔE1–2) of 2E2PEt and 2E3PEt were found to be larger than that of the previously synthesized ProDOT tetramer 4PHex. These co-oligomers gave the fairly stableradical cations 2E2PEt•+ and 2E3PEt•+ by chemical oxidation with AgSbF6. The disproportionation of 2E2PEt•+ and 2E3PEt•+ into neutral and dicationic species, which was observed for 4PHex•+, was inhibited

Nitronyl nitroxide (NN)‐substituted conjugatedoligomers, which were expected to self‐associate in biradical cation states, were designed to analyze the capability of π‐dimers as molecular wires. The oligomermoieties were composed of dithienyl‐N‐methylpyrrole with methoxy substituents at the inner β‐position of thiophene rings (DTP‐NN.) and its propylenedioxythiophene (ProDOT) inserted derivative
