The invention relates to copper(I) complexes of the formula (A)
with X═Cl, Br or I (independently of one another) N*∩E=bidentate ligand, with E=phosphinyl/arsenyl radical of the form R
2
E (where R=alkyl, aryl, alkoxy, phenoxy, amide); N*=imine function. Which is part of an aromatic group selected from pyridyl, pyrimidyl, pyridazinyl, triazinyl, oxazolyl, thiazolyl and imidazolyl, the aromatic group optionally having at least one substituent for increasing the solubility of the copper(I) complex in an organic solvent, and “∩”=at least one carbon atom, which is likewise part of the aromatic group, the carbon atom being located both directly adjacent to the imine nitrogen atom and to the phosphorus or arsenic atom, and also to the use thereof in optoelectronic assemblies, especially in OLEDs.
本发明涉及公式(A)的
铜(I)配合物,其中X = Cl,Br或I(彼此独立),N *∩E = 双齿
配体,其中E = R2E的膦基/
砷基基团(其中R = 烷基,芳基,烷
氧基,
苯氧基,
酰胺),N * =
亚胺基。它是从
吡啶基,
嘧啶基,
吡啶嗪基,三嗪基,
噁唑基,
噻唑基和
咪唑基中选择的芳基的一部分,该芳基可选择具有至少一个取代基,以增加
铜(I)配合物在有机溶剂中的溶解度,“∩”= 至少一个
碳原子,它同样是芳基的一部分,该
碳原子位于
亚胺氮原子和
磷或
砷原子直接相邻的位置,并且还适用于光电组件,特别是OLED中的使用。
