Photoswitchable Intramolecular Hydrogen Bonds in 5‐Phenylazopyrimidines Revealed By In Situ Irradiation NMR Spectroscopy

NMR spectroscopy with in situ irradiation uncovered unique photoswitchable intramolecular hydrogen bonds (IMHBs) in 5‐phenylazopyrimidines with two hydrogen bond donors. These compounds form two stable rotamers, each with one IMHB, and the rotamer ratio changes reversibly upon UV or visible light ir...
