The compounds were described using NMR (1H, 13C and 119Sn), IR, and elemental analysis. The compounds formed were assigned trigonal bipyramidal geometry depending on the spectrum data. Several Triorganotin (IV) tyrosine complexes were synthesized and mixed with polymers to form thin films (vinyl chloride). Up to 300 hours of UV light (wavelength: 313 nm) exposure was given to these films. A microscope, atomic force microscopy, and scanning electron microscopy were used to examine the surface morphology of the PVC films. Rapid UV-weathering was employed to determine weight loss and the production of certain functional groups, including carbonyl and polyene. Compared to pure PVC film, the films with manufactured complexes showed less undesired alterations. By absorbing UV light and scavenging peroxides, hydrochlorides and radicals. The polymer was photo stabilized by the triorganotin (IV)-tyrosine complexes (vinyl chloride). It was discovered that Ph3SnL has the fastest rate of PVC photostabilization. https://jpoll.ut.ac.ir/article_93024_35c9567923617820d758a209e3a352aa.pdf
