This interpretation will affect the results derived there for the Förster energy transfer radius

    • 2 is closed (refs 44, 45, 49, 52-54, and 58): only two sides of the kinetic triangle are operational in the excimer kinetics with 1Py(3)1Py. The emission bands of the two excimers are practically identical, but have different transient absorption spectra (refs 52-54). Consequently, the kinetic equation for the ratio φ′(exc)/ φ(mon) is more complex than that for the Scheme MD (M* ? D). The two intramolecular excimers of 1Py(3)1Py have practically identical emission bands (refs 44, 45, 49, 52, 53, and 58).

    • It was noted in ref 70 that two types of excimers with different overlap configurations of the naphthalene moieties are involved in the intramolecular excimer formation with 2Na(3)2Na, similar to what has been found with 1Py(3)1Py and other diarylalkanes (refs 44, 45, 49, 52, 53, 58, and 72). This condition leads to a more complex equation for the ratio φ′(exc)/φ(mon) than in cases where only one excimer is present (Scheme MD (M* ? D)), such as with 2Py(3)2Py (ref 5). This means that a data analysis based on the presence of only one excimer may lead to unreliable results
