pi-conjugated polymers find a range of applications in electronic devices. These materials are generally highly disordered in terms of chain length and chain conformation, besides being influenced by a variety of chemical and physical defects. Although this characteristic can be of benefit in certain device applications, disorder severely complicates materials analysis. Accurate analytical techniques are, however, crucial to optimising synthetic procedures and assessing overall material purity. Fortunately, single-molecule spectroscopic techniques have emerged as an unlikely but uniquely powerful approach to unraveling intrinsic material properties from the bottom up. Building on the success of such techniques in the life sciences, single-molecule spectroscopy is finding increasing applicability in materials science, effectively enabling the dissection of the bulk down to the level of the individual molecular constituent. This article reviews recent progress in single molecule spectroscopy of conjugated polymers as used in organic electronics.
π 共轭聚合物在电子设备中有着广泛的应用。这些材料在链长和链构象方面通常具有高度的无序性，此外还受到各种化学和物理缺陷的影响。尽管这种特性在某些器件应用中可能有益，但无序严重复杂化了材料分析。然而，准确的分析技术对于优化合成程序和评估整体材料纯度至关重要。幸运的是，单分子光谱技术已经成为一种不太可能但非常强大的方法，可以从底层揭示内在材料性质。在生命科学中这些技术取得成功的基础上，单分子光谱技术在材料科学中的应用越来越广泛，有效地实现了从整体到单个分子组成部分的剖析。本文综述了用于有机电子学的共轭聚合物的单分子光谱学的最新进展。
