液态有机半导体（Liquid organic semiconductors, LOSs）已成为下一代有机电子器件中极具吸引力的一类功能材料。2009年，Xu和Adachi提出了一种由有源层中的LOS组成的液体有机发光二极管（liquid OLED）。虽然有几篇论文报道了器件性能的改进，但从器件结构的角度来看，多色电致发光（EL）发射存在挑战。为了在一个衬底上集成多个单独的液体oled，我们开发了在两个电极之间夹有一微米厚微通道的多色微流体oled。本文简要介绍了作者在微流控有机发光二极管技术方面的最新进展，包括电-微流控器件的制造方法和利用芘基损耗的多色和白色发光二极管的演示。我们相信所提出的微流体oled在新型液体基器件应用中具有广阔的前景。
Liquid organic semiconductors (LOSs) have been an attractive class of functional materials for next generation organic electronic devices. In 2009, a liquid organic light-emitting diode (Liquid OLED), which consists of LOS in the active layer, was proposed by Xu and Adachi. Although several papers have reported on an improvement in device performance, from the viewpoint of the device architecture, there are challenges associated with multi-color electroluminescence (EL) emissions. In order to integrate multiple individual liquid OLEDs on one substrate, we have developed multi-color microfluidic OLEDs which have single-mu m-thick microchannels sandwiched between two electrodes. This paper presents a brief overview of the authors' own recent progress on the microfluidic OLED technologies, including fabrication methodology for electro-microfluidic devices and demonstration of multi-and white-color EL emissions using pyrene-based LOSs. We believe that the proposed microfluidic OLEDs can be promising for novel liquid-based device applications.
