✦ Synopsis
Colorless crystals of 1,4-dicyano-2-(4 0 -methoxybenzyloxy)methylnaphthalene (2), which is a 1,4-dicyano-2-methylnaphthalene (DCMN)-4-methylanisole (MA) dyad linked by an ether unit, selectively form a fluorescent intermolecular DCMN-MA exciplex (greenish blue, k exciplex f ¼ 456 nm). In contrast, 1,4-dicyano-2-(4 0 -methylbenzyloxy)methylnaphthalene (3), which is a DCMN-p-xylene dyad, forms a fluorescent intermolecular DCMN-DCMN excimer in the crystalline state (blue, k excimer f
