作为有机发光二极管(OLED)的发射体的包含碳烯配体的过渡金属配合物
摘要：
本发明涉及式(I)的过渡金属配合物在有机发光二极管中的用途，其中：M 1 是金属原子；碳烯是碳烯配体；L是一价阴离子或二价阴离子配体；K是中性的单齿或二齿配体，其选自膦、CO、吡啶、腈类以及与M 1 形成π配合物的共轭二烯；n是碳烯配体的数量，其中n至少为1；m是配体L的数量，其中m可以为0或≥1；o是配体K的数量，其中o可以为0或≥1；其中n+m+o之和取决于所用金属原子的氧化态和配位数，取决于配体碳烯、L和K的齿数以及取决于配体碳烯和L上的电荷，前提是n至少为1。本发明还涉及包含这类过渡金属配合物的OLED，包含这类过渡金属配合物的发光层，包含这种发光层的OLED，包含本发明OLED的器件，以及包含至少两种碳烯配体的特定过渡金属配合物。
摘要（英）：

The invention relates to the use of transition metal complexes of formula (I) in organic light-emitting diodes, wherein: M<1> represents a metal atom; carbene represents a carbene ligand; L represents a monoanionic or dianionic ligand; K represents a neutral monodentate or bidentate ligand selected from the group consisting of phosphines, CO, pyridines, nitriles and of conjugated dienes that form a pi -complex with M<1>; n represents a number of carbene ligands, whereby n is at least 1; m represents a number of ligands L, whereby m can be 0 or >= 1; o represents a number of ligands K, whereby 0 can be 0 or >= 1, and the sum n + m + o depends on the oxidation stage and coordination number of the metal atom used and on the dentation of the ligands carbene, L and K as well as on the charge of the ligands carbene and L, with the condition that n is at least 1.; The invention also relates to an OLED containing these transition metal complexes, a light-emitting layer containing these transition metal complexes, OLED's containing this light-emitting layer, devices that contain an inventive OLED, and to special transition metal complexes containing at least two carbene ligands.
