The synthesis, characterization and photostability studies of aluminum phthalocyanine chloride are hereby presented. Aluminum phthalocyanine chloride was synthesized by a solvent-free procedure involving microwave irradiation of a mixture of hydrated zinc chloride and 1,2-dicyanobenzene (phthalonitrile); the product was thoroughly purified and dried. The percentage yield was 83.4%. The characterization of the blue product was done via Fourier Transform IR Spectroscopy (FTIR) and UV-Visible spectrophotometry, and the results were satisfactory. In the FTIR spectrum, the formation of zinc phthalocyanine was confirmed by the band due to CN vibrations (around 2100 cm-1) which was present in the phthalonitrile (starting material), but absent in the product (aluminum phthalocyanine chloride). The UV-Visible absorption spectrum showed an intense signal at 672 nm and a weaker one around 350 nm. These bands are taken to be due to π→π* transitions within the phthalocyanine mol. The Beer-Lambert’s plot for the product resulted in a molar extinction coefficient value of 202,118 M-1 cm-1. Photodegradation studies showed that zinc phthalocyanine is very stable towards photoirradiation, with a rather small photodegradation value of 2.73 x 10-8.
