12种嘌呤类化合物的滤纸基质室温燐光法研究

Solid Surface Room Temperature Phosphorescence of Twelve Purine Derivatives

较为详细地研究了１２种嘌呤类化合物以滤纸为基质的室温燐光（ＲＴＰ）光谱特性与分子结构的关系，以及重原子效应和酸度效应对ＲＴＰ的影响。

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.
