Detailed O 1s spectra measured on samples with BDA with 1U- to 3U-phases and a molecular phase comprising pristine BDA molecules. Spectra were acquired in high magnification mode using the pass energy of 20 eV integrating up to 180 sweeps with 0.1 s dwell time and 0.05 eV energy step. See Supplementary Discussion, X-ray photoelectron spectroscopy analysis, for details on XPS analysis.
