摘要:

二维核磁技术(2D NMR)在复杂有机化合物结构的解析上起到重要作用. 通过分析2D NMR谱图关联信号可以得到分子内和分子间的相互作用信息. 有机光伏器件活性层材料之间相互作用的研究非常重要. 这种相互作用不仅可以用来分析活性层材料的聚集行为, 也可以用来分析活性层在加入第三组分后形貌及稳定性的变化, 为器件性能的研究提供强有力的工具. 本文对二维核磁技术进行了相关介绍; 总结了有机光伏领域中使用2D NMR研究分子间相互作用的相关工作; 最后, 展望了该技术的未来发展.

关键词: 二维核磁技术, 分子间相互作用, 聚集行为, 活性层形貌

Abstract:

Two-dimensional nuclear magnetic resonance technique(2D NMR) plays a crucial role in the structural analysis of complex organic compounds. Analyzing the correlation signals of 2D NMR spectra could help us obtain the information about intra- and inter-molecular interactions. Meanwhile, it is significant to study molecular interaction between photoactive layer materials for organic photovoltaics. Such interaction can help us not only analyze the aggregation behavior of molecules, but also understand the changes in the morphology and stability of the active layer upon the addition of a third component. In this review, we provide relevant introduction on the 2D NMR spectrum, and summarize the related works on the use of 2D NMR in the analyzing the interaction between molecules in organic solar cells. Finally, It offers a perspective on the future development in this technique.

Key words: Two-dimensional nuclear magnetic resonance, Intermolecular interaction, Aggregation behavior, Active layer morphology
