A photophysical study of the covalently linked tetracenedimer 1,4-bis(tetracen-5-yl)benzene is presented. While the dimer’s steady state spectroscopy is similar to that of monomeric tetracene, it also exhibits a long-lived fluorescence signal in solution and solid polyethylene films, which is absent in the monomer. The behavior of this long-lived component as a function of temperature and oxygenation
