Cover Feature: Influence of the Intramolecular Hydrogen Bond on the Fluorescence of 2‐ortho‐Aminophenyl Pyridines (Chem. Eur. J. 53/2022)
Intramolecular hydrogen bonds play an important role in the fluorescence of 2‐ortho‐aminophenyl pyridines, shifting the emission colour from deep blue to cold white. These multi‐emissive dynamic systems bearing excited‐state intramolecular proton transfer (ESIPT) moieties are susceptible to pH. The...

| Abstract | Intramolecular hydrogen bonds play an important role in the fluorescence of 2‐ortho‐aminophenyl pyridines, shifting the emission colour from deep blue to cold white. These multi‐emissive dynamic systems bearing excited‐state intramolecular proton transfer (ESIPT) moieties are susceptible to pH. The cover feature illustrates how DFT and td‐DFT calculations can elucidate why different levels of protonation lead to different emission colours. Photochemists are depicted as sailing through the waves of a spectrum. More information can be found in the Research Article by A. M. S. Silva, S. Guieu, and co‐workers (DOI: 10.1002/chem.202201844). |
