Single crystal X-ray analysis reveals a flat perylene π-scaffold for bisimide bearing bulky 2,6-diphenylphenoxy substituents at the 1,7 bay positions. The structure provides sharp vibronic progressions in absorption and fluorescence spectra, sterical shielding outstanding quantum yields solid state.
