Abstract

The electronic spectra of some polysilanes and their CT complexes with TCNE have been determined for the series: α, ω-(RO)3SiS(SiMe2)nSSi(OR)3 (n = 2, 3, 4, 6) and α-(RO)3SiS(SiMe2)nMe (n = 2, 4; R = i-Pr, t-Bu). Additional data for some related compounds are also presented. The results are discussed in terms of σ-silicon-silicon and σ-silicon-sulphur bond conjugation.
