Synthesis and unusual spectral properties of (alkoxycarbonyl)methyl-substituted polysilanes
UV-vis spectra of partially branched polysilanes having (alkoxycarbonyl)methyl substituents exhibit unusual spectral properties such as absorption of very long wavelength and temperature- and solvent-dependent change of the spectra. These observations suggest that polar substituents effectively promote the sigma -conjugation of the silicon backbones.
