37. In order to check if the differences observed were not caused by synthetical defects (the synthetic routes are significantly different), a third polymer, PF2/6 purchased from American Dye Source Inc., was investigated. The results obtained for this polymer were in good agreement with those for PF2/6, that were presented in this paper.
38. 0.5, where r is the diffusion radius, D is the diffusivity, and τ is the triplet lifetime. The diffusivity can be calculated from D = γ/4π · R, with γ being the annihilation parameter and R being the triplet extent.
39. The total magnitude of the PA signal of PF2/6 and especially the fact that the quadrature component is close to zero for slightly elevated temperatures make such an evaluation impossible for PF2/6.
