fluorene have been synthesized and their fluorescence properties analyzed. The synthesis of conjugated 2,7-bis(trimethylsilylethynyl)-(phenylethynyl)nfluoren-9-one (or the 9-(p-methoxyphenyl)-9-methyl) structures was carried out by the heterocoupling reaction between the 2,7-di(halo)fluoren-9-one (or 2,7-dibromo-9-(p-methoxyphenyl)-9-methylfluorene) and p-trimethylsilylethynyl(phenylethynyl)n (n=1,2), catalyzed
已经合成了2,7-取代的9-芴酮和9,9-二取代的芴,并分析了它们的荧光性质。通过2,7之间的杂偶联反应进行共轭2,7-双(三甲基甲硅烷基乙炔基)-(苯基乙炔基)n芴-9-(或9-(对甲氧基苯基)-9-甲基)结构的合成-二(卤)芴-9-一(或2,7-二溴-9-(对甲氧基苯基)-9-甲基芴)和对-三甲基甲硅烷基乙炔基(苯基乙炔基)n(n = 1,2),由二氯催化双(三苯基膦)钯和碘化亚铜体系,呈发散性合成。
