TL;DR: In this article, the physical processes responsible for the decay of the anisotropy were discussed, and the time-resolved fluorescence and fluorescence anisotropic measurements have been performed on solutions of high molecular weight polysilane materials.

TL;DR: In this article, the first two-photon excited fluorescence excitation spectra for polysilanes in solution, film, and low temperature glass were reported, and band-to-band and exciton models for the optical excitations were discussed in order to explain a strong twophoton resonance 0.9 eV above the first absorption band.

TL;DR: In this article, the authors reported the time-resolved fluorescence of polyaniline in NMP solution as a function of its average oxidation state which is continuously varied from the fully reduced leucoemeraldine base to the half-oxidized emeraldine base form of the polymer.

TL;DR: In this article, a description of the excited state dynamics following optical excitation in polysilanes is presented and the concept of conjugation length is discussed in relation to experiments on the saturation of excited state absorption signals observed at high excitation density.

TL;DR: In this article, an isolated rod-like phase of polysilane poly(di-n-hexyl-silane) poly(nhexyl) was shown to have a 4 times longer emission lifetime in crystalline compared to solution phases of the polymer, but the decay of anisotropy is essentially unchanged.
