Paper Abstract

Applications of conjugated polymers in photovoltaics and displays drive the need to understand how morphology affects emission and charge migration. Due to the inherent complexity of polymers, parallel studies of oligomer aggregates are required to ‘build-up' an understanding of the polymer features. Fluorescence lifetime imaging microscopy (FLIM) is used to probe variations in vibronic patterns and emission lifetime between individual aggregates and trends in these properties as a function of aggregate size. This technique yields insight into the structure and packing properties of these materials in the aggregated state.
