An efficient and scalable strategy to prepare libraries of discrete conjugated oligomers (Đ = 1.0) using the combination of controlled polymerization and automated flash chromatography is reported. From this two-step process, a series of discrete conjugated materials from dimers to tetradecamers could be isolated in high yield with excellent structural control. Facile and scalable access to monodisperse libraries of different conjugated oligomers opens pathways to designer mixtures with precise composition and monomer sequence, allowing exquisite control over their physical, optical, and electronic properties.
报道了一种使用可控聚合和自动化快速色谱相结合的高效、可扩展的策略来制备离散共轭寡聚物（Đ = 1.0）库。通过两步法，可以高产率、极好的结构控制分离得到一系列从二聚体到十四聚体的离散共轭材料。这种简单且可扩展的方法可以获得不同共轭寡聚物的单分散库，为具有精确组成和单体序列的设计混合物开辟了途径，从而可以对其物理、光学和电子性质进行精细控制。
