Synthesis, spectra, and complexing properties of polyoxyethylene-substituted 5,15-diphenylporphyrins
摘要:
Porphyrins with two opposite meso-phenyl substituents of the macroring linked via o-positions by polyoxyethylene bridges of various lengths were prepared. Their spectra and complexing properties toward Zn2+ and 1,4-diazabicyclo[2.2.2]octane were examined. The rate constants of formation and stability constants of the corresponding complexes were determined, and the concentration ranges of their formation were evaluated.
