An organic light emitting diode having a substrate, a first electrode, a hole transporting layer proximate the first electrode, a second electrode, an electron transporting layer proximate the second electrode, and an emissive layer between the hole transporting layer and the electron transporting layer. The emissive layer includes a square planar tetradentate platinum or palladium complex, and excimers formed by two or more of the complexes are aligned such that emitting dipoles of the excimers are substantially parallel to a surface of the substrate.
一种有机发光二极管,包括基板、第一电极、靠近第一电极的载流子传输层、第二电极、靠近第二电极的电子传输层和位于载流子传输层和电子传输层之间的发光层。该发光层包括一个正方形平面四齿配位的铂或钯配合物,由两个或更多配合物形成的激基复合物被排列成使激基复合物的发射偶极子与基板表面几乎平行的方式。
