Self-organized honeycomb (HC) polymer films were fabricated as a bottom-up assembly and deposited onto glass substrates in order to create extraction layers for blue OLEDs. Relying on the fast and tunable “Breath Figure” process, HC films were prepared on a minute time-scale and incorporated onto OLED devices, either through direct bottom-up formation onto the OLED substrates or through an original and convenient peeling/transfer method. Two types of HC films differing in period and morphology were prepared, and eventually led to an EQE improvement of 25% measured on an OLED whose emitter molecules are oriented parallel to the plane, using a vapor deposition at room temperature. Additionally, we have modeled the optical characteristics of the HC films, leaning on the fact they are periodic and very regular. This 3D optical model, complemented by a 1D electrical model to determine the Emission Zone Profile (EZP), predicts that the photonic films we fabricated are able to enhance up to 29% the EQE, and opens perspectives for a better design of extraction layers.

自组织蜂窝状（HC）聚合物薄膜被制造为自底向上的组件，并沉积在玻璃基板上，以创建用于蓝色OLED的提取层。依靠快速且可调的“呼吸图”工艺，可以在微小的时间范围内制备HC膜，并通过直接自底向上形成在OLED基板上或通过原始且方便的剥离/转移方法将HC膜结合到OLED器件中。制备了两种周期和形态不同的HC薄膜，最终通过在室温下进行气相沉积，在发射极分子平行于平面取向的OLED上测得的EQE提高了25％。另外，我们基于HC膜的周期性和非常规则的事实对HC膜的光学特性进行了建模。这个3D光学模型
