One- and Two-Dimensional Molecular Lattices

Two-dimensional monolayers and one-dimensional nanotubes can act as templates and containers for molecules and nanomaterials. We examine the formation of well-controlled molecular lattices inside nanotubes and on atomically flat two-dimensional substrates. We will show how in such lattices the optical molecular excitations couple into collective, delocalized excitons and vibrations. The coupling changes the energetics and dynamics of the collective states giving rise to effects such as superradiance and a strongly enhanced collective Raman response. We will examine how the interaction with the one- and two-dimensional hosts and substrates induce hybridized states with a particular emphasis on changes in the molecule-related response.
