pH-Dependent spin state population and 19F NMR chemical shift via remote ligand protonation in an iron(ii) complex

Abstract

An FeII complex that features a pH-dependent spin state population, by virtue of a variable ligand protonation state, is described. This behavior leads to a highly pH-dependent 19F NMR chemical shift with a sensitivity of 13.9(5) ppm per pH unit at 37 °C, thereby demonstrating the potential utility of the complex as a 19F chemical shift-based pH sensor.
