Abstract[English]
Provided are a spiro chiral tetradentate cyclometalated platinum (II) and/or palladium (II) complex circularly polarized luminescence material and the use thereof. For the formation of the spiro chiral metal complex molecule, a central chiral fragment in a ligand can autonomously induce the coordination of the entire tetradentate ligand with metal ions in a small steric hindrance manner, so as to form an optically-pure spiro chiral metal complex circularly polarized luminescence material. The induced reaction has stereospecificity, such that the spiro chiral metal complex does not require chiral resolution. The spiro chiral metal complex has significant application value in circularly polarized luminescence elements and related fields.[French]
L'invention concerne un matériau luminescent à polarisation circulaire de complexe tétradentate spiro-chiral cyclométallé de platine (ii) et/ou de palladium (ii) et son utilisation. Pour la formation de la molécule du complexe métallique spiro-chiral, un fragment chiral central dans un ligand peut induire de manière autonome la coordination de l'ensemble du ligand tétradentate avec des ions métalliques de manière à faible encombrement stérique, pour former un matériau luminescent à polarisation circulaire de complexe métallique spiro-chiral optiquement pur. La réaction induite a une stéréospécificité, de telle sorte que le complexe métallique spiro-chiral ne nécessite pas de résolution chirale. Le complexe métallique spiro-chiral présente une valeur d'application significative dans des éléments luminescents à polarisation circulaire et des domaines associés.[Chinese]
