Close and yet fluorescent : Derivatives of Pigment Yellow 101 can exhibit small intermolecular distances in the solid‐state crystal structures. Nevertheless, these compounds show strong solid‐state fluorescence. X‐ray structure determinations and elaborate quantum‐chemical calculations indicate that the unexpected fluorescence is a property of the individual molecules which is retained in the crystal. (Excited state energies are plotted along a CNN bending mode.)
