Abstract

A detailed study of the photophysics and photochemistry of the bichromophoric molecule 1,2-(bis-9-anthryl)-ethane (A2A) is presented. The ground- and excited-state potential energy hypersurfaces of A2A were calculated using semiempirical methods modified to account for the facile intramolecular excimer formation observed in this molecule. Temperature dependent fluorescence spectra were numerically resolved into the contributions from various underlying components using principal factor analysis. Thesesteady state results were combined with both time resolved experiments and the semiempirical calculations to identify and characterize the various excimer geometries.
