In this investigation, new 4-Tetra-4-Tolyl-Sulfonyl:Iron-Phthalocyanine (4T4TS-FePc) thin films' physical properties were examined using a variety of experimental conditions. The structural, morphological and optical properties of 4T4TS-FePc thin films were studied using different methods and also show that over appropriate heat treatment, it is possible to obtain 4T4TS-FePc films with a morphology tailored particularly to the desired needs including photocatalysis. According to the X-ray results, the film transfigures into a monoclinic ( β -phase) structure at an annealing temperature of 200 °C, and the reported diffraction peaks are subsequently lost at this phase shift. The material stands out from other compounds due to its qualities for thin-film mechanical and chemical stability. Subsequently, the methylene blue degrades quickly (to reaching 41.66%) when exposed directly to resilient visible radiation ( λ ≥ 400 nm) for more than six hours, which is consistent with the rest of the features of these hybrid compounds indicating their significant potential as a photocatalyst. As a result, its potential for applications is evident for the treatment of wastewater.
