Fig. 6. Predicted CO2 and N2 interaction energies (in kcal mol−1) for all molecules in the GDB-9 database using four molecular representation models.

Fig. 6

Only the model that utilized the PI molecular representation was able to identify 4,5-diamino-1H-imidazol-2-ol (inset) as the strongest CO2-philic groups (shown with an orange dot on each plot).
