四芳基卟啉化合物荧光性能的研究

Study of Properties of Tetaraary Porphyrin Compounds

研究了12种四芳基卟啉化合物的荧光性能.结果表明:该系列卟啉化合物具有较好的荧光性能;在1.0×10-5mol/L浓度下其荧光强度最大;供电子取代基能增加卟啉的荧光强度,而吸电子取代基作用相反;荧光强度随着取代基卤素原子量的增加而降低;此外,荧光强度还与取代基的位置及性质有关.

The fluorescence properties of 12 tetraarylporphyrin compounds were studied. It was found that the compounds has good fluorescence;contrary to electron-withdrawing groups, electron- donating groups on the phenyl groups of the compounds could increase their fluorescence intensities; with increasing atomic weight of halogen on the phenyl groups, the fluorescence intensity decreases; 1.0×10^-5mol/L was the best concentration to the fluorescence.
