Abstract

original image

A clever combination: A series of phenylene vinylene oligomers, in which the conjugated segments are held in a well-defined stacked arrangement along their entire length, was studied experimentally and theoretically (see picture). The impact of the extended interchain interactions on the photophysics of the π-stacked systems is reported.
