Novel ligands for metal complexes, where the ligands contain fused carbo or heterocycles on the quinoline building block are disclosed. More extended aromaticity within the molecule allows red shift when the molecules are used as light emitting dopants in organic light emitting diodes/devices.
金属配合物的新
配体中,
配体含有在
喹啉构建块上融合的碳框架或杂环。分子内更广泛的芳香性使得这些分子在有机发光二极管/器件中用作发光掺杂剂时发生红移。
