Polyfluorene Photophysics
The fundamental optical properties and processes that occur in the polyfluorenes are discussed. Details are given on the production of singlet and triplet excitons, their emissive decay channels via fluorescence and phosphorescence and non emissive decay via quenching, together with exciton lifetime...

| description | The fundamental optical properties and processes that occur in the polyfluorenes are discussed. Details
are given on the production of singlet and triplet excitons, their emissive decay channels via fluorescence
and phosphorescence and non emissive decay via quenching, together with exciton lifetime and quantum yields
of production. The interaction of excitons in these polymers is then discussed at length describing exciton
migration dynamics, exciton–exciton annihilation processes and delayed fluorescence and the trapping
of excitons at defect sites. Photogenerated charge state production is described along with intra-chain
charge transfer states in fluorene co-polymers. Finally, sections describing the optical properties of
the beta-phase of polyfluorene are given along with amplified spontaneous emission which occurs at high
beta phase exciton populations. |
