  摘要：

  A convenient and efficient synthesis of 3,5-di(silylethynyl)phenylacetylene and p-[3,5-di(silylethynyl)phenylethynyl]phenylacetylene has been carried out. These compounds serve to prepare nanometer-sized conjugated 1,4- and 1,3,5-phenylethynyl oligomers, by means of cross-coupling with a convenient haloaryl derivative, catalysed by palladium(H), in excellent yields. The phenylethynyl homologues show fluorescence emission, the wavelength of which is displaced by approximately 20 nm by each phenylethynyl unit increasing the conjugate chain.

  摘要：

  从3,5-二（三甲基甲硅烷基乙炔基）苯基乙炔和对-[3,5-二（三甲基甲硅烷基乙炔基）-1-乙炔基苯基]苯基乙炔开始，合成了纳米级共轭的1,4-和1,3,5-乙炔基苯基低聚物。钯（II）/铜（I）催化的方便卤代芳基衍生物交叉偶联反应，收率很高。通过特定的保护-脱保护方法有效地制备了末端乙炔。所获得的所有乙炔基苯基同系物均显示出荧光发射，每个乙炔基苯基单元的红移大约为20 nm，从而增加了共轭链。通过插入1，5-萘亚单元制备平行的共轭乙炔基苯基链，并且该化合物表现出荧光辐射发射。
