Synthesis, optical absorption and fluorescence of new poly(<i>p</i>‐phenylene)‐related polymers

Abstract

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.
