  • Synthesis, Optical, and Conductive Properties of Long Oligothiophenes and Their Utilization as Molecular Wires
    作者:Tetsuo Otsubo、Yoshio Aso、Kazuo Takimiya
    DOI:10.1246/bcsj.74.1789
    日期:2001.10
    This account reviews the current development of extraordinarily long oligothiophenes involving the 48-mer and 72-mer, which correspond to mono-disperse polymers. The systematic studies of the homologous series have provided valuable information on the optical and conductive properties of α-conjugated thiophene systems: an effective conjugation length extends to around 20 thiophene units in the neutral state and around 30 thiophene units in the oxidation state; this length plays a critical role in determining the electronic structures and conductivities. In addition, the active charge carrier species are both π-dimers and chain dimers, and charge transport occurs through the transfiguration of both species. This account also describes how useful oligothiophenes are as molecular wires allowing photoinduced electron- and/or energy-transfer. The molecular-wire behaviors of sophisticated oligothiophenes that are functionalized with a donor unit and an acceptor unit at the terminal α-positions are demonstrated.
    本报告回顾了涉及 48 聚体和 72 聚体(对应于单分散聚合物)的超长低聚噻吩的当前发展。同系物的系统研究为α-共轭噻吩体系的光学和导电性质提供了有价值的信息:有效共轭长度在中性态下延伸至约20个噻吩单元,在氧化态下延伸至约30个噻吩单元;这个长度在确定电子结构和电导率方面起着至关重要的作用。此外,活性电荷载体物种都是π-二聚体和链二聚体,并且电荷传输通过这两种物种的变形发生。该描述还描述了低聚噻吩作为允许光诱导电子和/或能量转移的分子线是多么有用。演示了在末端 α-位置用供体单元和受体单元功能化的复杂低聚噻吩的分子线行为。

  • Synthesis and Properties of a Series of the Longest Oligothiophenes up to the 48-mer

    A series of the longest class of oligothiophenes extended at intervals of seven thiophene units from the 6-mer up to the 48-mer has been synthesized by a combination of the random Eglinton coupling reaction of mono- and di-ethynylsexithiophenes and a subsequent sodium sulfide-induced cyclization reaction of the resulting oligo(sexithienylene-diethynylene)s. Their structures were well characterized by MALDI-TOF MS and 1H NMR spectroscopy. The molecular weights of the oligothiophenes and oligo(sexithienylene-diethynylene)s, measured by gel-permeation liquid chromatography using the polystyrene standard, are nearly double the actual ones, indicating that they keep highly rigid rod-type shapes. According to a molecular model, the molecular lengths of the longest oligothiophene 48-mer and the longest oligo(sexithienylene-diethynylene) reach approximately 18.6 nm and 25.0 nm, respectively. In the electronic absorption and emission spectra, the π–π* transitions of the oligothiophenes demonstrate progressive red shifts with increasing chain length up to the 20-mer. In the cyclic voltammograms, furthermore, the first oxidation potentials tend to continue negative shifts up to the 34-mer. In accordance with these spectral changes, the doped conductivities steadily increase and approach that of a structurally related polymer.
    通过单乙炔基和二乙炔基噻吩的无规埃格林顿偶联反应,以及随后硫化钠诱导的低聚(噻吩-二乙炔)环化反应,合成了一系列最长的低聚噻吩,这些低聚噻吩从 6-聚合体一直延伸到 48-聚合体,每隔 7 个噻吩单元。它们的结构通过 MALDI-TOF MS 和 1H NMR 光谱得到了很好的表征。以聚苯乙烯为标准,通过凝胶渗透液相色谱法测得的低聚噻吩和低聚(sexithienylene-diethynylene)s 的分子量几乎是实际分子量的两倍,表明它们保持着高刚性的棒状形状。根据分子模型,最长的低聚噻吩 48-mer 和最长的低聚(sexithienylene-diethynylene)的分子长度分别约为 18.6 nm 和 25.0 nm。在电子吸收光谱和发射光谱中,低聚噻吩的 π-π* 转变随着链长的增加而逐渐发生红移,直至 20-mer。此外,在循环伏安图中,第一氧化电位趋于继续负移,直至 34 个聚合物。根据这些光谱变化,掺杂后的电导率稳步上升,并接近结构相关聚合物的电导率。
