Project Gist

The rapid and precise structure analysis of organic amorphous thin films by using DNP-NM

Keywords

Dynamic nuclear polarization, Solid-state NMR, Organic device materials, Amorphous

Background and Purpose

The purpose of this project is the rapid and detailed analysis for organic device materials in an amorphous state by using DNP-NMR system that enhances the NMR sensitivity greatly. For this purpose, we form the collaborative research team with organic device researchers (Kyoto University) and DNP-NMR researchers in Europe. Since the DNP-NMR is applicable to a wide range of materials such as organic, inorganic and biomaterials, the introduction of DNP-NMR system is important for sustainable development of research ability in Kyoto University. Therefore, by acquiring the latest information on DNP-NMR in Europe, we also aimed to introduce DNP-NMR.

Project Achievements

Through the detachment of researchers in Europe, we could establish the international collaborative network for DNP-NMR. We also could gain insight about the installation of DNP-NMR system. Hence, we have applied for DNP-NMR system, and as the result, the introduction of DNP-NMR system is decided in next year in Kyoto University.

Future Prospects

We will further develop this international research network on DNP-NMR. Also, we aimed to construct basic science on organic devices through in situ DNP-NMR measurement of organic device.
