原始语种摘要: Abstract(#br)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, isolated in SnCl2 matrix, proved to be stable in the solid state and was characterized by MALDI‐TOF MS, 1H NMR, CPMAS 13C NMR, and absorption spectroscopy. An explanation for its reactivity in solution is proposed. The chromophoric properties in the visible region are shown to vary significantly and consistently along the series.
