Abstract

Cadmium acetate salts can greatly enhance room-temperature phosphorescence (RTP) of purine and 6-mercaptopurine. 6-Mercapto-substituent and 6-hydroxy-substituent appear quite different in their effect on the RTP of purine. The effects of cadium salt matrix and pH on the RTP of purine compounds were also investigated in detail. With cadmium acetate as a source of heavy atom perturbation, nanogram or subnanogram amounts of purines can be detected.
