Synthesis of bent-shaped π-extended thienoacenes from 2,5-distannylated 3,4-dialkynethiophene

Abstract

Bent-shaped thienoacenes show promise as next-generation organic semiconductors. Here we present the synthesis of an air-stable, pure and easily scalable thiophene precursor 2,5-distannylated-3,4-dialkyne thiophene starting from 3,4-dialkyne thiophene in quantitative...

Syntheses and properties of 11-ring-fused linear thienoacenes

“…22 Therefore, thienoacene and its derivatives have received more attention in recent decades. 23,24 With the advancement of organic synthesis methodologies, various thienoacenes with several aromatic rings were prepared (Fig. 1).…”
