Oligo(phenyleneethynylene)s 1 are rod-like compounds with undisturbed conjugation. In supplementation of the previously described members of this series 1a−e, with repeating units of up to n = 5, this work contains the preparation of higher oligomers 1f−i (n = 6, 7, 8, 10) through the use of the Sonogashira−Hagihara reaction. Both the absorption and the fluorescence bands showed convergence for increasing
低聚(亚苯基乙炔基) 1 是具有不受干扰的共轭的棒状化合物。作为对该系列 1a-e 之前描述的成员的补充,重复单元高达 n = 5,这项工作包含通过使用以下方法制备更高的低聚物 1f-i (n = 6, 7, 8, 10)园头-萩原反应。随着 n 值的增加,吸收带和荧光带均显示收敛,在有效共轭长度 nECL = 10 时达到极限值。 (© Wiley-VCH Verlag GmbH, 69451 Weinheim, Germany, 2002)
