用吸收光谱和发射光谱法研究了负电荷的锌四苯基卟啉磺酸钠与正电荷的紫精的络合作用,络合常数随紫精的疏水力而增长,在甲基紫精的敏光敏还原时,甲基紫精游离基阴离子平均产率随甲基紫精的起始浓度而增长,与Okura等的报导矛盾.

The complexation of the neg. charged. Zn tetraphenylporphyrin sulfonate with the pos. charged viologens was investigated by absorption and emission spectroscopy, resp. The complexation constant increases with the hydrophobicity of the viologen used. In the sensitized photoredn. of Me viologen the average rate of production of Me viologen radical cation for the 1st 15 min increased with the initial concentration of Me viologen, contrary to the initial rate reported by I. Okura et al. (1983, l985), which increases to a max. and then decreases with the increase of the initial Me viologen concentration
