This correlation heat map shows the importance of the static analysis based on the database in spite of data of 100 molecules. The HOMO/LUMO gap shows the negative correlation with the absorption wavelength (Abs_wl), VEA, and AEA strongly. Furthermore, the gap has the positive correlation with Stable2o2 (oxidation by O 2 ), VIP, and AIP. Hence, the HOMO/LUMO gap is a molecular property that dominates not only photochemical properties but also electronic properties.
