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
