The synthesis of three novel nonlinear optical (NLO) chromophores with threefold symmetry, namely 1,3,5-tris(4-N,N-diethylaminophenyl)-2,4,6-tris(4-nitrophenyl)benzene (3), 1,3,5-tris(4-N,N-dihexylaminophenylbutadiynyl)-2,4,6-tris(4-nitrophenyl)benzene (13) and 1,3,5-tris(4-N,N-dihexylaminophenylethynyl)-2,4,6-tris(4-nitrophenylethynyl)benze ne (4 b), is reported. We used the [Co(2)(CO)(8)]-catalysed
1,3,5-三(4-N,N-二乙基氨基苯基)-2,4,6-三(4-硝基苯基)苯(3)的三种对称的新型非线性光学发色团的合成, 1,3,5-三(4-N,N-二己基氨基苯基丁二炔基)-2,4,6-三(4-硝基苯基)苯(13)和1,3,5-三(4-N,N-二己基氨基苯基乙炔基)报道了-2,4,6-三(4-硝基苯基乙炔基)苯(4b)。我们使用[Co(2)(CO)(8)]催化的4-N,N-二乙氨基-4'-硝基甲苯(5)的三聚制备3。用1-(4-N ,N-二乙氨基苯基)-6-(4-N,N-硝基苯基)六亚炔(6)和[Rh(PPh(3))(3)Cl]得到13。使用逐步方法制备4b。在Pd(0)催化下,将1,3,5-Trichloro-2,4,6-triiododo苯(8 b)与4-硝基苯基-乙炔(14)偶联生成1,3,5-trichloro-2,4, 6-三(4-硝基苯基乙炔基)苯(15)。15与4-N,
