14. Stationary absorption and emission spectra of p-C1P4 in toluene. The spectral overlap is depicted in gray. Inset: The scheme representing singlet–singlet excitation hopping. 14. 5% are obtained for energy hopping. 15. 5 nm. It also allows us to see where in this three-dimensional picture the p-C2Pn series is situated. As the attachment of the chromophores to the dendrimer backbone in p-C2Pn cannot be taken as random, the value of k has been calculated from the threedimensional molecular structure using Eq.
However, the transient absorption signal of p-C1P3 is two times lower in intensity than that of p-C1P1. This suggests the occurrence of an additional decay channel, which in view of the results discussed earlier can be attributed to an ultrafast singlet–singlet annihilation process. The temporal evolution of the transient spectra of p-C1P3 and p-C1P1 is grossly different. It seems that the signal in the multichromophoric dendrimer at 530 and 650 nm decays faster when compared to p-C1P1. 27, where the transient absorption intensity as a function of time is plotted for p-C1P3 and p-C1P1 at detection wavelengths of 530 nm (top) and 650 nm (bottom).
