摘要:

A number of 5-arylazo-2-thiohydantoins (Ia … e) were prepared. The structure of the prepared materials is established by means of correct analytical data, infrared and electronic absorption spectra. Then the materials were subjected to an absorbed energetic γ-ray dose (5.0 × 107rd). The infrared and electronic absorption spectra of each material were measured after γ-irradiation. Upon γ-irradiation a considerable change occurs. Furthermore a sequence for the relative stability of the different dyes against γ-irradiation was established.
