- Abstract
The equilibrium solubility in benzene, tetrachloromethane, and ethyl acetate of octaphenyltetraazaporphine containing electron-acceptor (NO2) and electron-donor (Br) substituents in the phenyl rings was determined. In these solvents, p-substitution in aromatic rings with bromine considerably (by an order of magnitude and more) increases the solubility of porphyrins, whereas p-substitution with the NO2 group does not noticeably affect the solubility of the macrocycle in nonpolar solvents but increases the solubility in ethyl acetate by a factor of more than 200.
