The first examples of a novel family of sp‐carbon‐rich n‐π‐conjugated oligomers/polymers, namely carbo‐mers of polyacetylene, also referred to as “1,4‐PTA” isomers of the classical polytriacetylenes (1,2‐PTAs), are described in the perphenylated series. The two first representatives proved to be stable in solution, and exhibit a zig‐zag arrangement in the crystal state. The third member of the family
新型的富含sp碳的n - π共轭低聚物/聚合物家族的第一个例子,即聚乙炔的碳聚物,也称为经典聚三乙炔的“ 1,4-PTA”异构体(1,2- PTAs)在全苯基系列中有描述。最初的两个代表被证明在溶液中是稳定的,并且在晶体状态下呈锯齿形排列。该家族的第三个成员被分离在SnCl 2基质中,被证明在固态中是稳定的,并且具有MALDI-TOF MS,1 H NMR,CPMAS 13的特征。13 C NMR和吸收光谱。提出了其在溶液中的反应性的解释。可见区域中的发色性质沿该系列显着且一致地变化。
