Resumo(s)
The synthesis and spectroscopic characterisation of some representative N-alkylsubstituted
quaternary ammonium salts derived from benzothiazole, benzoxazole, benzoselenazole,
indole and quinoline are described. These heterocyclic salts, bearing an activated
methyl group in the 2-position in relation to the nitrogen atom and N-methyl, -pentyl, -hexyl
and -decyl chains, are typical precursors of cyanine dyes.
