A new class of gold(III) complexes with saturated poly(benzyl ether) dendrons has been synthesized, characterized, and applied as phosphorescent dopants in the fabrication of solution-processable organic light-emitting devices (OLEDs). The incorporation of the poly(benzyl ether) dendron into the cyclometalated gold(III) center can effectively perturb the packing of the molecules and minimizes the intermolecular interactions for suppressing excimeric emission. In addition, blue-green-emitting OLEDs can be realized, representing the first example of a blue-green-emitting device based on saturated dendrimer containing alkynylgold(III) complexes. Taking advantage of the diverse and well-developed synthetic routes for saturated dendrons, this work provides a simple means to develop a new class of gold(III) complexes emitting in the blue region.

新型的具有饱和聚（苄基醚）树突的金（Ⅲ）配合物，用于可溶液加工的发蓝绿色有机发光器件

已经合成，表征了新型的具有饱和聚（苄基醚）树枝状的金（Ⅲ）配合物，并将其用作磷光掺杂剂在可溶液加工的有机发光器件（OLED）的制造中。聚（苄基醚）树状分子掺入到环金属化金（III）中心可以有效地扰乱分子的堆积并使分子间的相互作用最小化以抑制激子发射。此外，可以实现发射蓝绿色的OLED，这是基于含炔基金的饱和树枝状大分子的发射蓝绿色的器件的第一个示例（III）复合体。利用饱和树枝状分子的多样且发达的合成路线，这项工作为开发在蓝色区域发射的新型金（III）配合物提供了一种简单的方法。
