Abstract
Heterocyclic azodyes of the pyridylazonaphthol and pyridylazoresoicino l series containing tuned hydrophobic chains have been prepared. Due t o their chelating properties, the dyes are suitable candidates for pre concentration and selective separation of transition metal ions. After a discussion on the choice of the best synthetic pathway, physical an d spectral uv/visible properties are presented and correlated with the structural features. A detailed analysis of nmr spectra allowed the c larification of currently unresolved signal assignments.
