Abstract
The synthesis and structural characterization of a europium complexed fluorene–bipyridine copolymer are described. A level of ion insertion of 80% in molar basis was achieved, and theoretical calculations showed that it required a twist of 179° (49 kJ) between the pyridine units. Spectroscopy data showed that no electronic coupling between the main backbone and the complexation sites had occurred, but these hindered the interchain aggregation observed in the non complexed polymer.
inary electroluminescence studies showed that the EL and PL spectra are consistent, and that the ion had a trapping effect in the charge transport.
