π-Extended Dipyrrolopyrazines as Multifunctional Materials

Abstract

Here, we report a convergent synthetic strategy employing a gold-catalyzed cyclization to construct novel π-extended dipyrrolopyrazine (EDPP) derivatives in a modular fashion. The robust design of EDPPs ensures high thermal stability, excellent oxidation resistance, and adaptability for integration into organic thin-film transistors and photoluminescent devices. Systematic exploration of substitution patterns revealed insights into structure-property relationships, particularly the influence of isosteric CH/N exchange. These findings establish EDPPs as a versatile platform for multifunctional materials, offering pathways for innovations in organic electronics.
