Preparation and characterization composite of hybris organic-inorganic material of bithiophene and tetraethoxysilane

Abstract

Preparation and characterization of hybrid organic-inorganic composite material of bithiophene and tetraethoxysilane were prepared from the reaction of 5,5'dibromobithiophene with tetraethoxysilane in tetrahydrofuran. The precursor of the reaction, bithiophene was prepared from the decoupling of bromothiophene in tetrahydrofuran with Ni Ch as catalyst. While 5,5' -dibromobithiophene compound was prepared from the reaction of bithiophene with N-bromosuccinimide (NBS) in the mixture of chloroform and acetic acid. The yield of the compound was tested by using the Infrared (IR) Spectrometry, Ultraviolet (UV) Spectrometer, 1H and 13C of Nuclear Magnetic Resonance (NMR).
