    • There ure two LE states for porphyrin structure (polarized X and Y). The reported electronic coupling data in this article were the average result of those two states.

    • The "exptl distance" column in Table 1 is based on the NMR data of molecule 2a (the same structure as 2a-Zn except without Zn); the "1low" in Tables 1 and 2 is based on the calculated structure using CHARMm, which is published in ref 24; the distance information of 1,8-diphenyl-naphthalene is from X-ray data of refs 49 and 50.

    • note
    • For la-Zn, we included all single excitations from the highest 26 occupied molecular orbitals (MOs) to the lowest 26 virtual MOs: IOr 2a-Zn we included all single excitations from the highest 34 occupied MOs to the lowest 34 virtual MOs; for 3a-Zn we included all single excitations from the highest 42 occupied MOs to the lowest 42 virtual MOs, and for 4a-Zn we included all single excitations from the highest 50 occupied MOs to the lowest 50 virtual MOs. The number was chosen based on analysis of the convergence of the electronic coupling. These excitations include CI excitations of bridge (π) to bridge (π*) and donor (π) Io bridge (π*). as well as the porphyrin and quinone local excitations.

    • note
    • It may seem that the D A distances for the PM3-based (2-3)a-Zn structures are smaller than those for the DFT-based structures. However, that is because the axis through the centers of the phenyl and quinonyl rings is not perpendicular to the porphyrin plane, not because of tighter stacking of the rings. This can be proven by the fact that the D-A center-to-center distance of PM3-based structures is always about I Å larger than that in DFT-based structures.
