Synthesis and photoactivated insecticidal activity of tetraethynylsilanes

A series of tetraethynylsilanes (TETS) have been synthesized by reaction of silicon tetrachloride (SiCl4) with Ar-C{triple bond, long}CLi, which was prepared in situ by treatment of Ar-C{triple bond, long}CH with n-BuLi. For these TETS thus pre

Synthesis of conjugated 2 and 2,5-(ethenyl) and (ethynyl)phenylethynyl thiophenes: Fluorescence properties

Nano conjugated thienylethenyl and thienylethynyl compounds with controlled structure and dimensions have been efficiently prepared, by heterocoupling reaction between 1,4-(thienylethynyl)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(phenylethynyl)nthiophene 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.

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

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 ter
