Webphotoinduced charge transfer occurs at the interface between the two materials while an energy transfer towards the chain with the lowest optical transition takes place in the second case. In this context, we model here the properties of two homogeneous blends of PPV chains recently investigated by the Cambridge group [20]. Charge-transfer bands are a characteristic feature of the optical spectra of many compounds. These bands are typically more intense than d–d transitions. They typically exhibit solvatochromism, consistent with shifts of electron density that would be sensitive to solvation.
