Abstract:Heteroacenes developed to widely used building blocks in organic semiconductors for application in organic electronics due to their tunable structures and properties concomi¬ant with inherent stability. Here, we report efficient preparation and investigation of so far unknown heterotriacenes, basic anti- and syn-dithienopyrazines 5 and 6. The comparison of the two isomers with respect to electronic properties and follow-up reactions gives insights into structure-property and -reactivity relationships. Examples… Show more
