Description
Summary:The acid-base properties of 5,10,15,20-tetraphenyl-21-oxaporphyrin and 5,10,15,20-tetraphenyl-21,23-dioxaporphyrin have been studied by means of spectrophotometric titration. The parameters of electronic absorption spectra and the concentration ranges of the existence of the obtained forms have been determined. Kinetics of the formation of complexes of 5,10,15,20-tetraphenylporphine oxa derivatives with copper at 288–308 K has been studied.
