Resumo

The luminescence and thermochromic properties of a europium-containing metallopolymer were investigated in experimental and theoretical aspects using the same polymer backbone complexed with two different contents of europium ions (25 and 65% molar). The polymer presented an emission insensitive to temperature variation which was attributed to a balance between two factors: the first is the ``stiffening effect{''} on the polymer backbone brought about by ion complexation, and the second is the interconnection of the alkyl chains because of the rotation of the bipyridine sites required for the complexation.
