    • Our MM calculations, using the MM2 force-field, were crude and course-grained, and we didn't pursue more refined MM calculations as they didn't fall within the purview of the study reported herein. However, since the submission of this manuscript, Professor Peter Boyd kindly calculated the conformations of 1 using the UFF force-field.

    • In both the MP2 and the LMP2 calculations, the core MOs were frozen.

    • We recently attempted to optimize the geometry of the complex 2 using the same functional and basis set used by Boyd et al., [5] as implemented in ADF 2002. Unfortunately, the optimization had not converged to a minimum energy structure, even after 300 cpu hours on a supercomputer. During the attempted optimization, the interchromophore separation, R, (see 2), mainly varied between 3.2 and 3.6 Å at no stage did R fall below 3 Å.

    • The DIM-LMP2 method should recover ca. 95% of the correlation energy, compared to the MP2 method, whereas the TRIM-LMP2 method should recover ca. 99% of the correlation energy [37].
