Enthalpies of dissolution of tetrapyridylporphyrin (TPyP) derivatives, in which the pyridine nitrogen is located in para-, meta- or ortho-positions and is modified by nonpolar (-CH₃,-C₂H₅,-C₃H₇), polar (-CH₂COOH, -CH₂CH₂COOH) and low-polar (-CH₂COOC₂H₅) groups, are determined in water by calorimetric method for the first time. The factors, making considerable impact in enthalpies of dissolution of the studied compounds in water, are revealed.

Keywords: Tetrapyridylporphyrin, dissolution enthalpies, interparticle interaction.
