Abstract

The authors have studied the dynamics of photoexcitations in chiral assemblies of p-phenylenevinylene oligomers functionalized with H-bonding motifs. In the regime of low excitation densities, the luminescence transients are influenced by the migration of excitons to defect sites, indicative of fast diffusivity of excitons along the mol. assemblies. At high excitation densities, bimol. exciton annihilation results in the fast depopulation of the stacks' excitonic energy levels. [on SciFinder (R)]
