The prepared aniline-indium(III) porphyrin chromophoric systems were successfully characterised by using FT-IR spectroscopy, 1 H NMR spectroscopy and ESI-mass spectrometry. The 1 H NMR and UV-Visible absorption spectroscopic studies of aniline-indium(III) porphyrin systems were further recorded as a function of pure aniline concentration in proper solvents. The results of these spectroscopic studies indicate the existence of interchromophoric interactions between aniline and indium(III) porphyrins which increase with the increase in pure aniline concentrations. Powder X-ray diffraction (PXRD) measurement data reflects change in crystalline phases of parent complexes upon incorporation of aniline molecules. Thermogravimetric analysis (TGA) indicates that aniline-incorporated indium(III) porphyrins are less thermally stable than their parent complexes.
