Wj. Jin et al., COMPARISON OF ROOM-TEMPERATURE PHOSPHORESCENCE PROPERTIES OF 3 PURINECOMPOUNDS WITH CADMIUM ACETATE AS A SOURCE OF HEAVY-ATOM PERTURBATION, Applied spectroscopy, 49(3), 1995, pp. 320-323
Cadmium acetate salts can greatly enhance room-temperature phosphoresc
ence (RTP) of purine and 6-mercaptopurine. 6-Mercapto-substituent and
6-hydroxy-substituent appear quite different in their effect on the RT
P of purine. The effects of cadium salt matrix and pH on the RTP of pu
rine compounds were also investigated in detail. With cadmium acetate
as a source of heavy atom perturbation, nanogram or subnanogram amount
s of purines can be detected.
