| abstract |
The invention relates to a diazonium aryl salt devoid of hydroxyl functions of the following general formula (1):n nX −+ N≡N-A-R 1 —(OR 2 ) n —O—R 4 -A′-N≡N + X − (1)n nin 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, BF 4 —, NO 3 —, HSO 4 —, PF 6 —, CH 3 COO—, N(SO 2 CF 3 ) 2 —, CF 3 SO 3 —, CH 3 SO 3 —, CF 3 COO—, (CH 3 O)(H)PO 2 —, and N(CN) 2 —;n nR 1 , R 2 and R 4 are identical or different and are independently selected from the group consisting of —CH 2 —, a cyclic alkyl group, an acyclic alkyl group, a linear alkyl group, and a branched alkyl group; andn nA 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. |
