“…In the late 1980s, there was a discussion in the literature about the existence of the naphthalene triplet excimer. − Nowadays, many works support the formation of triplet excimers of dinaphthyl compounds under various conditions. − ,, In the experimental work by Terazima, Cai, and Lim, covalently linked naphthalene dimers were studied using time-resolved electronparamagnetic resonance (TREPR), phosphorescence, and transient absorption measurements . From the interpretation of these spectra, they suggested that these compounds form triplet excimers.…”
