系列羟基苯基卟啉在碱体系中的性质

Properties of a Series of Hydroxyphenylporphyrins in Alkali

利用紫外-可见光谱、拉曼和红外光谱研究系列羟基苯基卟啉在碱体系中的性质.结果表明,碱与羟基苯基卟啉周边的羟基发生反应形成盐,而与卟啉中心环上的H没有相互作用,说明羟基苯基卟啉分子的中心环比较稳定,电荷主要分布在周边meso-位的取代基上,该位置易发生反应.

We studied the properties of a series of hydroxyphenylporphyrins in alkali via UV-Visible,infrared spectroscopy and Raman spectroscopy. It was found that in the base system,the alkali reacted with the peripheral hydroxyls of hydroxyphenylporphyrin,forming the salt,while no interaction between alkali and H on the center of the porphyrin ring took place. This result proves that the center ring of the hydroxyphenylporphyrin ring was stable,electric charges of the porphyrin were mostly distributed on the circumambient substituent on the meso-position where reaction easily took place react.
