Abstract
Multibranched pi-conjugated materials and hyperbranched polymers have received considerable interest in both academic research and industrial applications because of their unusual molecular structures and properties. In this communication, we provide an efficient approach to synthesize two novel pi-conjugated multibranch compounds, which have good solubility and are nanosize (about 5 nm). The double bonds of the multibranch compounds are synthesized using solvent-free Wittig-Horner-Emmons reactions. The reaction conditions are simple and mild. Their optical properties are discussed too.
