Abstract

The photo- and electroluminescent properties of a copolymer containing fluorene, terpyridine and complexed sites with trivalent europium ions (LaPPS66Eu) was investigated. The non-complexed backbone (LaPPS66) and an analogous chemical structure of the ligand/Eu3+ site (LaPPS66M) as a model compound were used for comparison and interpretation of the photophysical properties. Experiments were carried out using PVK as a dispersive matrix either in a blend form or in a bilayer configuration. Absorption and emission spectra, time-resolved emission spectra (TRES) and Forster Resonance Energy Transfer efficiency (< E-FRET >) were used to account for the differences found for the photophysical properties of each configuration.
