Abstract
The influence of the polarity of the medium on the efficiency of Type I and Type II photosensitization as carried out by hematoporphyrin and its derivative Photofrin II was studied by EPR techniques. Our results suggest that porphyrin aggregates do not participate as such in the photosensitized processes. Thus, the solvent-induced breakdown of the aggregated components of Photofrin II appears to determine the photosensitizing efficiency of this porphyrin.
摘要
利用电子顺磁共振（EPR）技术研究了介质极性对血卟啉及其衍生物光敏素II所进行的I型和II型光致敏效率的影响。我们的结果表明，卟啉聚集体本身并不参与光致敏过程。因此，溶剂诱导的光敏素II聚集成分的分解似乎决定了这种卟啉的光致敏效率。
