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 invention relates to a “push-pull” type compound, used for manufacturing polymer materials having both electrical conduction and photochromic properties, which responds to the general formula A-X-R in which:
A is an electron acceptor group;
X is a group having a π-conjugated system and forms a photochromic group with A; and
R is a polymerizable electron-donor group that is chosen among the carbazole group and the groups derived from the carbazole group by substitution, and which is linked to X by the nitrogen atom of the carbazole group.
The invention also relates to an electroconducting and photochromic polymer material, obtained by polymerization of this compound.
Applications: optoelectronics, signal processing, data storage, etc.
