Chain aggregation in electroluminescent polymers such as MEH-PPV has a profound effect on their emission and charge transport characteristics. However, detailed study of the spectroscopic effects of aggregation is hampered by the lack of structure in the electronic spectrum. Here we present studies of aggregates of shorter-chain oligomers of MEH-PPV that exhibit highly structured emission both at the bulk and single aggregate level. Trends are seen in the emission intensity and Franck-Condon structure as a function of chain length and are modeled to obtain an understanding of the inter-molecular interactions in the aggregate species.
