Abstract
Quaternized tetra(4-pyridyl)porphine derivatives: tetra(N-carboxymethyl-4-pyridyl)porphine tetrachloride, tetra(N-carboxymethyl-4-pyridyl)porphine tetrabromide, tetra(N-methyl-4-pyridyl)porphine tetraiodide, and tetra(N-ethoxycarbonylmethyl-4-pyridyl)porphine tetrachloride, were synthesized, isolated, and purified. The enthalpies of solution of these compounds in water at 298.15 K were determined calorimetrically. The effect of functional substituents in porphyrin ligands on the enthalpies of solution is discussed.
