End-capping of conjugated thiophene–benzene aromatic systems

Synthesis of Ladder-Type Thienoacenes and Their Electronic and Optical Properties

“…Similar and smaller analogues of the FBT molecules based on benzothiophenes (BTs) have been previously reported. 48,50 Their emission profiles resembled those of the FBT molecules, and an increase in the Q.Y. as the conjugation became longer was also found.…”

“…Additionally, the anti geometry of the sulfur atoms in the FBT molecules prompted effective π conjugation and contributed to the observed high Q.Y. Similar and smaller analogues of the FBT molecules based on benzothiophenes (BTs) have been previously reported. , Their emission profiles resembled those of the FBT molecules, and an increase in the Q.Y. as the conjugation became longer was also found.…”

High-performance five-ring-fused organic semiconductors for field-effect transistors

“…Wex et al synthesized isomerically pure anti-and syn-TBBT via Bradsher cyclization. [283][284][285] Yasuda et al analyzed the isomeric effect on the charge transport properties for both unsubstituted and alkyl-substituted TBBT. The results indicated that the better self-assembly ability of the syn-position (syn-TBBT-8, 177, Fig.…”

Design and synthesis of hybrid cyclophanes containing thiophene and indole units via Grignard reaction, Fischer indolization and ring-closing metathesis as key steps

“…As part of a major program aimed at developing new and intricate strategies to cyclophanes [2–10], we envisioned various building blocks [11] by ring-closing metathesis (RCM) as a key step [12–25]. Cyclophanes containing different heterocyclic systems are difficult to assemble [26–31].…”
