molecules with a silyl group and an aromatic core surrounded by extended π conjugative arms has been synthesized by the use of Sonogashira coupling methods. They show excellent fluorescence intensity with high quantum yield. These molecules undergo desilylation in the presence of nBu4NF to give terminal polyalkynyl compounds. By incorporating metal moieties such as palladium, platinum and gold into these
已经通过使用 Sonogashira 偶联方法合成了一系列具有甲硅烷基和芳香核的星形分子,这些分子被扩展的 π 共轭臂包围。它们显示出优异的荧光强度和高量子产率。这些分子在 nBu4NF 存在下进行脱甲硅烷基化,得到末端聚炔基化合物。通过将钯、铂和金等金属部分掺入这些化合物中,可以获得星形分子。在溶液中用光谱法研究这些分子的光物理特性。这些星形分子通过 IR、NMR(1H、31P 和 13C)光谱以及 MALDI-TOF 质谱进行表征。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
