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

摘要

A series of 2,5-diethynylsilole derivatives anti their polymers, prepared by the Stille coupling reaction, show unique optical properties such as long-wavelength absorptions in their UV-vis absorption spectra. [References: 29]
