分析了中性条件下在水溶液及盐溶液中系列双亲卟啉随其浓度连续变化的紫外-可见吸收光谱。结果表明,在中性条件下不同侧链取代基对双亲卟啉的聚集行为有很大影响,盐的加入导致卟啉的聚集形态发生改变,初步解释了影响卟啉聚集的原因。 The UV-vis absorption spectra of a series of amphipathic porphyrins with varying concentrations in aqueous solution and saline solution were analyzed. The results showed that under the neutral conditions, different side chain substituents had a great influence on the aggregation behavior of the amphipathic porphyrins. The addition of salt led to the change of aggregated morphology of porphyrin, which explained the reasons that affect the aggregation of porphyrins.
