Silole-acetylene π-electronic systems with low bandgaps: Synthesis, structure, and UV-vis absorption spectra of 2,5-diethynylsiloles derivatives and their polymers

Article abstract of DOI:10.1246/cl.1998.89

A series of 2,5-diethynylsilole derivatives and their polymers, prepared by the Stille coupling reaction, show unique optical properties such as long-wavelength absorptions in their UV-vis absorption spectra.
