Abstract
In order to observe the physiological properties of styryl dyes, a comparatively simply compounds of photosensitive heterocyclic ammonium salt dyes, over 30 kinds of dyes were obtained by the condensation of aromatic aldehydes and aromatic heterocyclic ammonium salts in EtOH solution under the presence of piperidine. Ammonium salts used were synthesized from lepidine, 6-methoxylepidine, quinaldine, 4-aminoquinaldine, 2, 4-dimethylthiazole, α-picoline, γ-picoline, 2, 4-lutidine and 2, 6-lutidine with alkyl halides such as ethyl, propyl, butyl and octyl bromides and methyl iodide. Aldehydes used were benzaldehyde, piperonal, vanillin, furfural, p-dimethylaminobenzaldehyde and anisaldehyde.
