| Abstract: | In this paper,we studied the electronic absorption spectra of 5-(p-hydroxyphenyl)-10,15,20-triphenylporphyrin in glacial acetic acid The experimental results showed that 5-(p-hydroxyphenyl)-10,15,20-triphenylporphyrin exist in equilibrum between the diacid form H 4L 2 and the free base form H 2L: H 4L 2 =H 2L 2H |
