Abstract
AbstractNew oligomers based on quinoxaline units were successfully synthesized through multistep reactions using Wittig coupling, affording (E)‐(quinoxalin‐2‐yl)ethene oligomers. Diverse quinoxaline‐based phosphonium salts were designed and synthesized, enabling versatility and compatibility regarding the oligomer‐building process. The characterization of the oligomers showed excellent stereoisomer specificity, i.e., a fully E‐configurated conjugated π‐system. The oligomers’ light absorption/emission profiles indicate potential properties for an application in materials science.
