OCELOT is an open-source database composed of organic molecular crystals extracted from the CSD and contributions from the community. Crystal structures are restricted to single-component, non-polymeric organic molecules without metal ions, and the existence of at least two aromatic rings in the π-conjugated backbone. The database is part of the Organic Semiconductors by Computationally Accelerated Refinement (OSCAR) project, which seeks to accelerate materials discovery through computational methods. The OCELOT database consistes of 9479 organic molecular crystals with DFT-calculated bandgaps, with the settings described in Section 3.3. Unlike the previous section, calculations for the OCELOT database were performed using the Vienna Ab-Initio Simulation Package (VASP) software. The average bandgap of the database is 2.31 eV, as seen in Figure . OCELOT includes 476 sets of polymorphs, with 1248 polymorphs total.
