| Popis: | 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. |
