| Abstract: | The solid surface room temperature phosphorescence (SS-RTP) of twelve purine derivatives using China-made filter paper as solid substrate was given. The relation between molecular structure and spetrum, the effects of heavy atoms and acidity on RTP were studied in detail. The experimental results showed that purine derivatives have analogous spectra. The maximal excitation wavelengths were round 280 nm, the maximal emission wavelengths were round 430 nm. For purine derivatives I- is a widely used heavy atom. The effect of pH on RTP intensity is related to the molecular structure. |
