Synthesis, characterization, and stability of poly(ethylene-co-acrylic acid) films surface functionalized with fluorescent moieties

Light emission has been introduced onto poly(ethylene-co-acrylic acid) (PEAA) surfaces by covalently grafting two different fluorescent moieties. The facile surface modification method presented allows commercial polymers to be used for light emitting and sensor applications. Two fluorescent compounds, 4′-(octyloxy)-4-biphenyl carboxylic acid (OBC) and 2,7-bis (bromomethyl)-9,9-dihexyl-9H-fluorene (BMDF), were covalently grafted to the surface...
