  Synthesis of conjugated 2-arylethynyl and 2-arylethenyl thiophene structures with optical properties

  摘要：

  Conjugated mono(arylethynyl)oligothiophene structures have been obtained starting with (E)-[1-(2'-thienyl)-2-(p-phenyl)]ethyne (E)-7 and 2-[p-(iodophenyl)ethynyl]thiophene 8. Conjugated nanostructures were synthesized by oxidative coupling between the terminal acetylenes (E)-7 and 8 to give, respectively, 1,4-di[(2-p-(iodophenyl)ethynyl)thienyl]-1,3-butadiyne and 1,4-di[(2-p-iodophenylethynyl)thienyl]-1,3-butadiyne. All the thiophene derivatives synthesized show an important fluorescence radiation emission, with a bathochromic shift, which increases with the conjugation of the chain. (C) 2004 Elsevier Ltd.

  Nano conjugated thienylethenyl and thienylethynyl Compounds with controlled Structure and dimensions have been efficiently prepared, by heterocoupling reaction between 1,4-(thienylethynylphenyl)phenylacetylene (or thienylethenyl)phenylacetylene and 2- or 2,5-dihalothiophene. Conjugated 1,4-di(2-thienylethynylphenyl)- (or 2-thienylethenylphenyl)-1,3-butadiyne were obtained by the homocoupling of the terminal acetylenes in excellent yield. The end-capped (N,N-dimethylaminophenyl)- and [3,5-di(trimethylsilylethynyl)-1-ethynyl]-2,5-di(iodo)thiophene were obtained by the heterocoupling between the corresponding terminal acetylene and 2,5-di(iodo)thiophene, catalyzed by the bis(triphenylphosphine)palladium and cuprous iodide system in excellent yield.
