In this work, a bicyclo[4.4.1]undecane scaffold is used to hold oligo(phenyleneethynylene) units in a cofacially stacked arrangement along the entire length of the conjugated units. We study the impact that the resulting strong interchain interactions have on the photophysical properties. The length of the individual oligomer branches was varied from three to five rings to investigate the effect of
