To understand the trends in coverage, we utilized pEDA once more (Figure ). Dispersion and electrostatic interactions get stronger when additional molecules are added. The orbital interaction ΔEorb is becoming less favorable by ΔΔEorb = 45, 109 kJ mol -1 and 136 kJ mol -1 , and the preparation energy ΔEprep(surf) is increasing by ΔΔEprep(surf) = 15, 69 kJ mol -1 and 41 kJ mol -1 for B, C, and D respectively. The Pauli repulsion ΔEPauli increases with ΔΔEPauli = 60, 29 kJ mol -1 and 205 kJ mol for B, C and D. With this massive increase of Pauli repulsion, D is unfavorable and thus are all configurations above θ = 0.25 since there will always be molecules at adjacent 4-rings. Therefore, the ideal, maximum coverage is 0.25 for interface formation in the conformation B, with the electrostatic and dispersion contribution compensating for the increase in Pauli repulsion.
