Abstract
The green emission (g-band) in polyfluorene-based conjugated materials is studied by various spectroscopic methods on defined poly(9,9′-dioctylfluorene) with one foluorenone unit (P20), which can be seen as a model compound for polyfluorene emitting g-band. The absorption and emission properties of P20 in the film and solution (room temperature) reveal the optical properties of the green emission emerging in polyfluorene-type polymer. All the experimental evidence obtained demonstrates that g-band in polyfluorene is attributed to the mono-chain fluorenone; and the aggregation of the chains further suppresses the blue emission and enhances g-band.
