Polyferrocenylenesilynes, hyperbranched polymers

Figure 4 Absorption spectra of hyperbranched polyferrocenylenesilynes pc ri(p-Cn3d2m+ ) Si] - [ (m) =8 18] in dichloromethane. The spectra of the partially soluble polymers 1(1) and 1(V) are not given because it was difficult to accurately determine their solution concentrations and molar absorptivities. The spectral data for a THF solution of linear poly[l,l -ferrocenylene(dimethyl)silene] [5(1)] is shown for comparison.
