Photo-ejected ligands hyperpolarized by parahydrogen in reversible exchange.

ABSTRACT: Hyperpolarization derived from signal amplification by reversible exchange (SABRE) is valued for its relative simplicity among hyperpolarization approaches. Here, we demonstrate that photoejection of the ligands pyridazine and pyrazine from prodrug Ru(II) polypyridyl complexes offers a new modality for activating SABRE hyperpolarization, achieving enhancements of over 3200-fold.
