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.

与我们的工业合作伙伴共同准备：该项目旨在改进限制有机电子器件中使用的有机材料寿命的电荷感应过程的表征。在所有有机电子器件中，电荷引起的分子降解是器件故障的一种途径。 重复的充电循环会降低有机层的性能，因此需要更换。现代表面科学显微镜可以在带正电或负电的情况下观察相关有机材料的单个分子。 拟议的研究将通过实验确定由此产生的成分变化，并为其理解和控制提供详细的理论基础。我们提出的研究将涉及有机电子新兴行业的所有领域，这些领域正在创新以实现有机太阳能电池、有机发光二极管和有机场效应晶体管等器件的商业化。 在这些应用中的每一个中都会遇到电活性分子，例如本研究中重点关注的那些。
