Photoluminescent phenanthroimidazole derivatives as covalently linked UV stabilizers for latex coatings

Year: 2025

Abstract: Suzuki cross-coupling with high yield up to 85%. The synthesized monomers were characterized by multinuclear NMR, FTIR spectroscopy, and single-crystal X-ray diffraction analysis. PPI derivatives, in amounts ranging from 0.05 to 1 wt% (based on monomers), were copolymerized with methyl methacrylate, butyl acrylate, and methacrylic acid using a standard emulsion polymerization technique. The resulting coatings were fully transparent in the visible region and were characterized by UV-vis and photoluminescence measurements. Dynamic mechanical analysis demonstrated that DV-bPPI and DV-PPI, at concentrations of 0.5-1 wt% and 0.25-0.5 wt%, respectively, effectively prevented UV-induced degradation of the polymer films.
