Abstract

The synthesis and properties of soluble, conjugated polymers consisting of oligo(p‐phenylene) sequences linked by ethylene, vinylene, or ethylene, units are reported. Benzene‐, stilbene‐, diphenylacetylene‐ and 1,2‐diphenylethane derivatives serve as monomers and are connected by the Suzuki‐coupling method. A wide range of poly‐(p‐phenylene)‐related polymers are available by the combination of different AA/BB‐type monomers in various concentrations. The optical properties of the resulting polymers can therefore be tailored. Number‐average degrees of polymerization of up to X̄~n~ = 137 were reached under optimized conditions. Photoluminescence quantum yields of these materials in solution are nearly one.
