Abstract[English]
The present invention relates to the technical field of the preparation of circularly polarized luminescent materials, and particularly relates to a spiro-chiral tetradentate platinum (II) and/or palladium (II) complex circularly polarized luminescent material based on pyridine-carbazole-phenyl carbene and a derived structure thereof, and the use thereof. By means of a remote central chiral fragment within the chiral substituted pyridine, the provided complex molecule can autonomously induce the entire tetradentate ligand to coordinate with metal ions in a less sterically hindered manner, so as to form an optically-pure spiro-chiral metal complex circularly polarized luminescent material. Such a spiro-chiral metal complex circularly polarized luminescent material does not require chiral resolution, and has high molecular thermodynamic stability and important applications in circularly polarized luminescent elements.[French]
La présente invention relève du domaine technique de la préparation de matériaux luminescents à polarisation circulaire, et concerne en particulier un matériau luminescent à polarisation circulaire du complexe tétradentate spiro-chiral de platine (II) et/ou de palladium (II) à base de pyridine-carbazole-phényl carbène, une structure dérivée de celui-ci et une utilisation associée. Un fragment chiral central distant au sein de la pyridine chirale substituée permet à la molécule du complexe selon l'invention d'induire de manière autonome l'ensemble du ligand tétradentate pour se coordonner avec des ions métalliques selon un mode moins encombré stériquement, ce qui permet de former un matériau luminescent à polarisation circulaire de complexe métallique spiro-chiral optiquement pur. Un tel matériau luminescent à polarisation circulaire de complexe métallique spiro-chiral ne nécessite pas de résolution chirale, et présente une stabilité thermodynamique moléculaire élevée et des applications importantes dans des éléments luminescents à polarisation circulaire.[Chinese]
