End-capping of conjugated thiophene–benzene aromatic systems
摘要:
The synthesis of end-capped thieno[3,2-f:4,5-f']bis[1]benzothiophene was achieved from thiophene and 2,5-thiophenedicarboxaldehyde. Specifically, hexyl and dodecyl end-capping groups conferred reversible redox behavior as evidenced by cyclic voltammetry with oxidation potentials of 0.73 V versus Fc/Fc(+) couple. An extensive spectrophotometric analysis is reported. (c) 2010 Elsevier Ltd. All rights reserved.
