Synthesis and luminescence studies of poly(vinyl acetate)-Eu (III) coordination compound

In this research, the polymeric coordination compound of PVAc-Eu (III) was synthesized, and the formation of coordination bonding between Eu (III) and the carbonyl oxygen in PVAc was investigated by Fourier transform infrared (FT-IR) spectroscopy, Raman spectroscopy (RS), and X-ray photoelectron spectroscopy (XPS). The luminescent characteristics/properties of the prepared PVAc-Eu (III) were studied using fluorescence spectroscopy (FS). The results indicated that (1) the interaction/ association between PVAc and Eu (III) in the prepared PVAc-Eu (III) was coordination bonding instead of weak physical adsorption, and (2) the photoluminescence intensity of PVAc-Eu (III) was approximately three times that of EuCl3. This research provided a theoretical foundation for the potential use of PVAc-Eu (III) as an innovative polymeric luminescent material, particularly for the applications in areas such as adhesives, coatings, textiles and others, the areas in which PVAc is an important raw material.
