Abstract[English]
Disclosed in the present invention are a central chirality remotely induced spiro-chiral tetradentate cyclometalated platinum(II) and/or palladium(II) complex-based circularly polarized luminescent material, and a use thereof. The provided spiro-chiral tetradentate cyclometalated complex molecule can autonomously induce the entire tetradentate ligand to coordinate with metal ions in a low-steric-hindrance manner by means of a remote central chiral fragment in a chiral-substituted pyridine, thereby forming an optically pure spiro-chiral metal complex-based circularly polarized luminescent material. The spiro-chiral metal complex-based circularly polarized luminescent material requires no chiral resolution, has a high molecular thermodynamic stability, and is of significant practical value in circularly polarized luminescent elements.[French]
La présente invention concerne un matériau luminescent à polarisation circulaire à base de complexe cyclométallé tétradentate spiro-chiral de platine (II) et/ou de palladium (II) induit par effet à distance de chiralité centrale et son utilisation. La molécule du complexe cyclométalé tétradentate spiro-chiral selon l'invention peut induire de manière autonome l'ensemble du ligand tétradentate pour se coordonner avec des ions métalliques d'une manière à faible encombrement stérique au moyen d'un fragment chiral central par effet à distance dans une pyridine substituée chirale, formant ainsi un matériau luminescent à polarisation circulaire à base de complexe métallique spiro-chiral optiquement pur. Le matériau luminescent à polarisation circulaire à base de complexe métallique spiro-chiral ne nécessite pas de résolution chirale, présente une stabilité thermodynamique moléculaire élevée, et présente une valeur pratique significative dans des éléments luminescents à polarisation circulaire.[Chinese]
