Electronic Structure of disordered LCOF. Electronic structure in LCOFs is sensitive to the layer stacking order. For example, it was shown for COF-5 that different small-UC models, AA s inc , AA s serr yield electronic structures of significant differences in band gap and dispersion. Therefore, we have evaluated the electronic structure of COF-1 and COF-5 in statistical stacking order. As a compromise between good statistics and computational costs, we have built multilayered bulk "snapshots" of disordered LCOF structure. Due to the low symmetry the band structures become crowded, so we focus on the densities-of-states (DOS) differences.
