| Abstract |
Diethyl or dihexylbis(phenylethynyl)silane as precursor were prepared by reactions of dichlorodiethyl or dihexylsilane with of phenylacetylene treated with n-butyllithium in situ.
2,5-Dibromo-1,1-diethyl or dihexyl-3,4-diphenylsilole as monomers were prepared by the intramolecular reductive cyclizations of diethyl or dihexylbis(phenylethynyl)silane with treatments of lithium naphthalenide and followed by reaction with anhydrous ZnCl2 and N-bromosuccinimide in situ.
The obtained silole derivatives are soluble in usual organic solvents such as THF and CHCl3. The prepared materials were characterized by 1H, 13C NMR, and FT-IR spectroscopies along with TGA. We also studied the electronic properties by UV-vis absorption, excitation and fluorescence emission spectroscopic methods along with electrochemical property, in particular.
