Conjugated polymers phosphorescent polymer light-emitting

It is believed that the molecules of these metalated complexes are totally planar. This allows a better 7t-conjugation across the main chain. The ligands are strongly fluorescent but may become phosphorescent when the platinum atom is introduced in the backbone. These optical properties are tracked back to Ttn transitions by a two-photon absorption. The potential for the use of such metallopolymers for electrophospho-rescent polymer light-emitting devices has been discussed [75].
