Charge Transfer and Excimer Formation

Nature volume 200, pages 766–767 (1963)Cite this article

Abstract

THE general properties of excited dimers, or excimers, have been well established1–4. In concentrated solutions of some polycyclic aromatic hydrocarbons, a singlet excited molecule can interact with an unexcited neighbour to produce the excited dimer, or excimer. This excimer can then break up into de-excited monomer molecules with the emission of a characteristic dimer fluorescence. The forces binding the dimer have been ascribed by Forster5 to resonance dipole interaction. The criterion has been given for excimer formation that the molecule should possess a weak 1Lb level lying beneath a strong 1La level. Most of the excimer-forming molecules obey this criterion, a notable exception being anthanthrene.
