Triplet Dynamic Nuclear Polarization

During the 66th session of the Global NMR Discussion Meetings held on May 2nd, 2023 via Zoom, Prof. Nobuhiro Yanai gave a talk on the topic "Triplet Dynamic Nuclear Polarization: New Polarizing Agents and Targets". The recording serves as a tutorial.

Abstract:
Triplet dynamic nuclear polarization (triplet-DNP), which utilizes the polarized electron spins of the photo-excited triplet, is an excellent method to obtain large nuclear spin polarization even under mild conditions below 1 T near room temperature. This talk will highlight the potential of triplet-DNP and the exciting new possibilities that have emerged with recent advancements in polarizing agents and targets. Specifically, I will cover the following topics:

1. Mechanism of triplet-DNP as an introduction
2. Expanding the targets using supramolecular polarizing agents
3. Improving air stability and solubility with non-pentacene polarizing agents
4. Challenging polarization transfer with the use of nanomaterials.

Nobuhiro Yanai is an Associate Professor, Department of Chemistry and Biochemistry, Kyushu University, Japan.
