Abstract
Sharp and intense excitonic photoluminescence is observed at low temperatures in highly uniform pentacene monolayers deposited on a compliant polymeric substrate. The free exciton (FE) emission displays characteristic intensity that grows quadratically with the number of monolayers N. The energy of the FE band redshifts with increasing N revealing impact of molecular overlap on the FE state.
