Abstract The results of the study of the complexation of 5,10,15,20-tetra(4-chlorophenyl) porphyrinate zinc with 1.4-diazabicyclo(2.2.2)octane in chloroform-d and benzene-d6 at different ratios of molar concentrations of porphyrinate and substrate by 1H NMR spectroscopy and the spin-lattice relaxation time measurement (500 MHz) are presented.The dominant relaxation mechanism was established. The equilibrium constant for the complexation reaction was estimated.
