Abstract

Poly(phenylenevinylene) (PPV) grafted with triethylenetetramine (TETA), PPV:TETA, unlike PPV, can interact with anionic sulfonated polymer dyes and can also coordinate metal ions, eg Eu, by chelation with the grafted TETA moiety. We have used these interactions and chelation to construct two types of self-assembled films using the layer-by-layer self-assembly technique. Structural characterization by means of specular X-ray reflectivity of heterostructures containing PPV:TETA:Eu showed that in self-assembled films containing metal ions there is a clear Bragg reflection (up to the third harmonic) indicating the formation of well modulated heterostructures. Photoluminescence (PL) measurements of heterostructures containing PPV:TETA and anionic polymer dyes showed evidence for energy transfer between the PPV:TETA and the polymer dyes.
