Single-chain fluorinated Ir-NHC catalysts for efficient SABRE pyruvate hyperpolarization with average residual iridium below 100 ppb

Year: 2026

Type: article

Abstract: Efficient SABRE for biomedical use requires minimal metal contamination. We report a new class of single-chain fluorinated Ir–NHC catalysts; one matches the performance of IMes for 13 C pyruvate hyperpolarization and enables Ir removal to <100 ppb.
