“…Similar patterns were observed for other porphyrin conjugates with terpenylphenols: the main inhibitory effect of porphyrin molecules with phenolic substituents is due precisely to the hydroxyl group of the phenol fragment and, consequently, their RSA essentially depends on the composition and location of the substituents in the phenol fragment [ 22 , 23 , 24 , 25 ]. The structure of the porphyrin part of the conjugate has a significant effect on the value of the stoichiometric inhibition coefficient ( f ).…”

This article focuses on the antiradical activity of a number of 2,6-diisobornylphenol-porphyrin conjugates with various spacers between the porphyrin and phenolic fragments in the model reaction of ethylbenzene oxidation initiated by azoisobutyric acid dinitrile. The study has shown that the electronic effects of the groups directly related to the 2,6-diisobornylphenol fragment exert the predominant influence both on the reactivity of the phenolic hydroxyl group in interaction with free radicals and on the antiradical activity of the molecule as a whole. The antiradical activity of the molecule is generally less affected by the nature of the substituents in the porphyrin macrocycle, mainly due to a change in the stoichiometric inhibition coefficient in the presence of relatively easily oxidizable groups. It was found that the length of the spacer between the porphyrin and phenolic fragments does not affect the antiradical activity of the conjugate.
