Exciton and biexciton signatures in the femtosecond transient absorption of phenylene-based polymers and oligomers

Conference ·
OSTI ID:658367
The femtosecond transient absorption of phenylene-based polymers at low intensities is dominated by singlet excitons. In films, inter-chain excitons are created at high intensities via two-exciton states. In solution, the authors observe signatures of stable biexcitons.
