Using fluorescence microscopy of oligomer aggregates to understand the properties of conjugated polymers used in photovoltaic devices

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

Chain aggregation in electroluminescent polymers such as MEH-PPV has a profound effect on their emission and charge transport characteristics. Here we present studies of aggregates of shorter-chain oligomers of MEH-PPV, CN-PPV, and polythiophene that exhibit highly structured emission both at the bulk and single aggregate level. Trends are seen in the emission intensity, fluorescence lifetimes, 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.
