The invention relates to 1,7-diarylpentamethine and 1,9-diarylheptamethine salts, in partricular heptacarbon or nonacarbon carboxonium salts, and streptocyanines.
The compounds correspond to formula [G-D-G′]
+
Q
−
in which Q is an anion of a strong acid, and
G and G′ represent, independently of each other, an OEt, amino, hydrazono, hydrazino, phosphaimino, amidino or guanidino group; or a multivalent radical optionally linked at at least one of its other ends to another group D;
D represents a cationic group 1,7-diarylpentamethine or 1,9-diarylheptamethine in which the aryl groups carry substituents representing, independently of each other, a hydrogen, a halogen, an alkyl radical or an alkyloxy radical having from 1 to 15 carbon atoms or an acetamido group CH
