The absorption spectra of H TPP

[23] obtained similar absorption spectra for H2TPP dissolved in chloroform solvents.
The influence of temperature changes on the thermal and structural behavior of crystalline solvates of H2TPP with 1,4-dioxane and of CuTPP with benzene were investigated using X-ray diffraction, thermogravimetry and differential scanning calorimetry techniques [24]. X-ray diffraction measurements showed pancreas desolation in benzene caused a minor decrease in the volume of the unit cell containing the same number of CuTPP molecules.
