Synthesis of Bridged Oligothiophenes: Toward a New Class of Thiophene-Based Electroactive Surfactants
摘要:
A series of bridged oligothiophenes have been synthesized. Their novel molecular architecture, comprising two oligothiophenes linked together by a bridge at one a-extremity and one binding group at the other a-extremity, is expected to improve their utility as electroactive surfactants for semiconducting nanoparticles or organic electronics.

Fine-tuning the solid-state ordering and thermoelectric performance of regioregular P3HT analogues by sequential oxygen-substitution of carbon atoms along the alkyl side chains
observed when doping with FeCl3 in nitromethane at room temperature, and so is their thermoelectric performance. The highest power factor of 19 μW m−1 K−2 was observed for the doped P3POET film, which presents a dominant edge-on orientation with the strongest crystallinity and the closest π–π stacking. At the doping time corresponding to the optimized power factors (PFs) for each polymer, the doped P3POET
