Abstract

Chainlike polysilanes, which consist of a linear silicon-catenated backbone and organic side chains, exhibit unique optical properties due to the silicon σ-conjugating electronic structure. Among these polysilanes, it has been established that rodlike polysilanes bearing a special pair of chiral and/or achiral alkyl side chains have unique (chir) optical features due to the highly delocalized silicon σ electrons associated with very long segment lengths. The author describes several marked cooperative phenomena of optically active rodlike polysilane homopolymers and copolymers bearing (S/R) -2-methylbutyl or (S/R) -3, 7-dimethyloctyl chiral side chains by means of UV, circular dichroism (CD), and fluorescence (FL) spectra and molecular mechanics calculation.
