Aryl diazonium salt and use in an electrolytic solution of an electrochemical generator

Abstract

The invention relates to a diazonium aryl salt devoid of hydroxyl functions of the following general formula (1):XN≡N-A-R—(OR)—O—R-A'-N≡NX  (1)in which: n is in a range of from 1 to 10, preferably from 1 to 4, Xrepresents a counter-ion of the diazonium cation selected from the group consisting of halogenides, BF—, NO—, HSO—, PF—, CHCOO—, N(SOCF)—, CFSO—, CHSO—, CFCOO—, (CHO)(H)PO—, and N(CN)—;R, Rand Rare identical or different and are independently selected from the group consisting of —CH—, a cyclic alkyl group, an acyclic alkyl group, a linear alkyl group, and a branched alkyl group; andA 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.
