Abstract The synthesis of dendrons with the end-capped 5-( N , N -dimethylamino)naphthyl-1-ethynyl unit connected to conjugated naphthylethynyl or p -phenylethynyl chains, as the branches of the 1,3,5-substituted benzene core, have been undertaken by heterocoupling reaction between 1,3,5-triiodobenzene and the convenient end-capped 5-( N , N -dimethylamino)naphthylacetylene or 5-( N , N -dimethyla
摘要 以 5-( N , N - 二甲基氨基) 萘基-1-乙炔基单元连接到共轭萘乙炔基或对苯乙炔基链,作为 1,3,5-取代苯核心的支链,合成树枝状化合物,在钯-铜催化剂存在下,通过 1,3,5-三碘苯与方便的封端 5-(N,N-二甲氨基)萘乙炔或 5-(N,N-二甲氨基)萘乙炔基苯乙炔之间的杂偶联反应进行系统,产量高。已经分析了交替的萘乙炔基-苯乙炔基链对树突结构中荧光发射辐射的影响。
