The invention relates to a diazonium aryl salt devoid of hydroxyl functions of the following general formula (1): X−+N≡N-A-R1—(OR2)n—O—R4-A′-N≡N+X−  (1) in which: n is in a range of from 1 to 10, preferably from 1 to 4, X− represents a counter-ion of the diazonium cation selected from the group consisting of halogenides, BF4—, NO3—, HSO4—, PF6—, CH3COO—, N(SO2CF3)2—, CF3SO3—, CH3SO3—, CF3COO—, (CH3O)(H)PO2—, and N(CN)2—; R1, R2 and R4 are identical or different and are independently selected from the group consisting of —CH2—, a cyclic alkyl group, an acyclic alkyl group, a linear alkyl group, and a branched alkyl group; and A and A′ are identical or different and independently represent a mono or polycyclic, aromatic hydrocarbonated group chosen from the group formed by phenyl, aryl groups, condensed polyaromatic groups, which may be substituted. |
