Abstract[English]
The present invention relates to the technical field of circularly polarized luminescent material preparation, and in particular to a spirochiral tetradentate platinum(II) complex-based circularly polarized luminescent material based on pyridine-carbazole-phenylcarbene and a derivative structure thereof, and an application thereof. The provided complex molecule autonomously induces, by means of a remote stereocenter-containing fragment in chirally substituted pyridine, an entire tetradentate ligand to coordinate with a metal ion in a less sterically hindered manner, so as to form an optically pure spirochiral metal complex-based circularly polarized luminescent material. Such spirochiral metal complex-based circularly polarized luminescent material does not require chiral resolution, has high molecular thermodynamic stability, and has important applications in circularly polarized light-emitting components.[French]
La présente invention se rapporte au domaine technique de la préparation de matériau luminescent à polarisation circulaire, et concerne en particulier un matériau luminescent à polarisation circulaire à base de complexe de platine (II) tétradentate spirochiral à base de pyridine-carbazole-phénylcarbène, une structure dérivée de celui-ci, et son utilisation. La molécule du complexe fournie induit de manière autonome, au moyen d'un fragment contenant un stéréocentre distant dans de la pyridine substituée par voie chirale, un ligand tétradentate entier pour se coordonner avec un ion métallique d'une manière moins stériquement encombrée, de façon à former un matériau luminescent à polarisation circulaire à base de complexe métallique spirochiral optiquement pur. Ledit matériau luminescent à polarisation circulaire à base de complexe métallique spirochiral ne nécessite pas de résolution chirale, présente une stabilité thermodynamique moléculaire élevée, et présente des applications importantes dans des composants électroluminescents à polarisation circulaire.[Chinese]
