چکیده

Ground state properties and excited states of ladder-type paraphenylene oligomers are calculated applying semiempirical methods for up to eleven phenylene rings. The results are in qualitative agreement with experimental data. A new scheme to interpret the excited states is developed which reveals the excitonic nature of the excited states. The electron-hole pair of the S1-state has a mean distance of approximately 4 Å.

Ultrafast excited state absorption and charge separation in phenylene-based conjugated polymers

Ultrafast pump-probe spectroscopy of phenylene-based -conjugated polymers give low and high energy photoinduced absorptions (PAs) to final states with very different relaxation behavior. While the low energy two-photon state that is reached in PA relaxes to the optical exciton in ultrafast times, the higher energy two-photon state violates the Vavilov–Kasha rule and instead of relaxing to the o...

Excitons in poly(para phenylene vinylene): a quantum-chemical perspective based on high-level ab initio calculations.

Excitonic effects play a fundamental role in the photophysics of organic semiconductors such as poly(para phenylene vinylene) (PPV). The emergence of these effects is examined for PPV oligomers based on high level ab initio excited-state calculations. The computed many-body wavefunctions are subjected to our recently developed exciton analysis protocols to provide a qualitative and quantitative...

Excitonic effects in a time-dependent density functional theory.

Excited state properties of one-dimensional molecular materials are dominated by many-body interactions resulting in strongly bound confined excitons. These effects cannot be neglected or treated as a small perturbation and should be appropriately accounted for by electronic structure methodologies. We use adiabatic time-dependent density functional theory to investigate the electronic structur...

Photophysics of a poly„phenylenevinylene... with alternating meta-phenylene and para-phenylene rings

We have investigated the photophysics of the luminescent polymer poly~1,3-phenylenevinylene-alt-2,5dioctyloxy-1,4-phenylenevinylene! by a variety of optical spectroscopies. The incorporation of alternating meta-phenylene and para-phenylene rings restricts conjugation with respect to poly~para-phenylenevinylene! derivatives. As a consequence, excited states are blueshifted and the nonlinear susc...

Excitation Transfer in Poly-(p -phenylene Vinylene)

Electroluminescent conjugated polymers such as poly-(p-phenylene vinylene) (PPV) are at the brink of being extensively used commercially as light emitting devices. A continuous flow of both theoretical and experimental studies elucidate many still unresolved issues of polymer photophysics. Among the processes under debate are the different energy transfer pathways. This work studies one such pa...
