A series of novel pyrazolyl-substituted 1,3,4-thiadiazole derivatives (6a-6d, 7a-7d, 8a-8d) were prepared by cyclization of the intermediate 3-aryl-l-phenyl-pyrazol-4-ylformaldehyde 4′-phenylthiosemicarbazones with 0.5 M ferric chloride solution. The structures of the new compounds were confirmed by IR, 1H NMR and elemental analysis. Simultaneously, the compounds were detected by fluorescence spectrophotometer and had preferable fluorescence activity.
