Three donor-acceptor type host materials with different photophysical properties were developed by managing the interconnect position of the donor and acceptor moieties and molecular structure of the host materials was correlated with the electro-optical properties and device performances of the host materials. The linkage via the meta-position of aromatic units was better than the linkage via ortho- or para-positions and high quantum efficiency of 26.0% in the green thermally activated delayed fluorescent device was achieved using the host material with the meta-linkage.
通过控制供体和受体部分的互连位置，开发了三种具有不同光物理性质的供体-受体型主体材料，主体材料的分子结构与主体材料的电光性质和器件性能相关。通过芳环单元间位的连接优于邻位或对位的连接，使用具有间位连接的主体材料在绿色热激活延迟荧光器件中实现了26.0%的高量子效率。
