Zusammenfassung

We report on a systematic study on the reactivity of the pyrylium dye Py-1 toward various classes of amines (primary aliphatic, primary aromatic, secondary, tertiary) and its use in environmental sensing of amines. While most primary aliphatic amines react almost quantitatively with Py-1 within 10 min, sterically hindered primary aliphatic amines and primary aromatic amines react more slowly. ...
