Charge-Induced Degradation of Organic Layers

与我们的工业合作伙伴共同准备：该项目旨在改善限制有机电子设备中使用的有机材料寿命的电荷诱导过程的特征。在所有有机电子器件中，电荷诱导的分子降解是导致器件失效的一种途径。反复充电循环会降解有机层，需要更换。现代表面科学显微镜允许观察相关有机材料的单个分子，同时受到正电荷或负电荷的影响。这项拟议的研究将从实验上确定由此导致的成分变化，并为理解和控制它们提供详细的理论基础。我们提出的研究将触及新兴有机电子行业的所有领域，该行业正在创新，将有机太阳能电池、有机发光二极管和有机场效应晶体管等设备商业化，仅举几例。在这些应用中，每一种都会遇到电活性分子，如本研究中所关注的那些。

Prepared in conjunction with our Industrial Partner: This project is directed toward improved characterization of the charge-induced processes limiting the lifetime of organic materials used in organic electronic devices. In all organic electronic devices, charge induced molecular degradation is a pathway for device failure. Repeated charging cycles degrade the organic layer, necessitating replacement. Modern surface-science microscopy permits observation of individual molecules of the relevant organic materials, while subjected to positive or negative charging. The proposed research will identify the resulting changes in composition experimentally, and provide a detailed theoretical basis for their understanding and control. Our proposed research will touch all areas within the emerging industry of organic electronics that is innovating to commercialize devices such as for example, organic solar cells, organic light emitting diodes, and organic field-effect transistors, to name some. In each of these applications electro-active molecules such as those focused on in this study are encountered.
