Abstract 1,1-Diisopropyl(or 1,1-Diphenyl)-3,4-diphenyl-2,5-bis(trimethylsilyl)siloles were prepared by the intramolecular reductive cyclizations of diisopropyl(or diphenyl)bis(phenylethynyl)silanes with treatment of 4.5 mol lithium naphthalenide and followed by 4 mol chlorotrimethylsilane solution in THF. After the reaction was finished, the naphthalene was removed via naphthalene sublimation apparatus, and the crude product was purified by recrystallization. The obtained materials are soluble in usual organic solvents such as THF and CHCl3. The prepared materials were characterized by NMR, and IR spectroscopies. We also studied the electronic properties of the prepared silole derivatives by UV-vis absorption, excitation and fluorescence emission spectroscopic methods, in particular. In order to study the electrochemical properties of the synthesized materials, we also prepared a composite of the obtained carbosilanes with silicon nano powder, and examined the electrochemical properties.
