Alternating (1-naphthylethynyl-p-phenylethynyl)x 1,3,5-trisubstituted benzene dendrons were efficiently synthesised by the heterocoupling reaction between (1-naphthylethynyl-p-phenyl)xacetylene (x = 1) and 1,3,5-triiodobenzene in the presence of a palladium-copper catalyst system. A longer terminal acetylene chain (x = 2) was obtained from the heterocoupling between 1,3,5-tri(1-ethynyl-5-naphthylethynyl)benzene
通过(1-萘乙炔基-p-苯基)x乙炔(x = 1)和1,3,5-之间的杂偶联反应有效地合成了交替(1-萘乙炔基-对苯基乙炔基)x 1,3,5-三取代苯树枝状化合物在钯-铜催化剂体系存在下的三碘苯。从 1,3,5-三(1-乙炔基-5-萘乙炔基)苯和适当的碘芳基衍生物之间的杂偶联获得更长的末端乙炔链 (x = 2)。交替链及其树枝状结构显示荧光发射,具有相似的波长和量子产率。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)
