Abstract: The intramolecular exciplex fluorescence was observed in two (9, 10- dicyanoanthracene)-(CH2) 3-(naphthalene) systems in polar and nonpolar solvents, in which activation energies for the exciplex formations were obtained. Only in the nonpolar solvent was another fluorescence observed in the longer wavelength region below-150 K than the exciplex fluorescence, and it was ascribed to the intramolecular charge-transfer ...
