摘要
研究了12种四芳基卟啉化合物荧光性能的取代基效应。结果表明,卟啉化合物的苯基上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;荧光强度随着卟啉的苯环上取代基卤素原子量的增加而降低;此外,荧光强度还与卟啉的苯环上取代基的取代位置有关。
Substituent effects on the fluorescence properties of 12 tetraarylporphyrin compounds were studied. Contrary to electron-withdrawing groups,electron-donating groups in the phenyls of the compounds increase the fluorescence intensities, and decrease with atomic weight of halogens. The fluorescence intensity of porphyrin also relates to the substituent positions on the phenyl groups.
