Photoswitchable, metal-free parahydrogen-induced polarization enabled by a phosphorus biradicaloid

Year: 2025

Type: article

Abstract: Visible light-controlled nuclear spin hyperpolarization was demonstrated in parahydrogen activation using a metal-free phosphorus biradicaloid photoswitch. Experiments demonstrated an efficient photoresponse of the observed hyperpolarization. Two orders of magnitude signal enhancements were observed at 9.4 T. The mechanistic details of the underlying processes are provided.
