  通过双电子共振直接观察低聚芴分布中的链长和构象

  摘要：

  合成聚合物是不同长度链的混合物，它们的链长和链构象通常通过整体平均进行实验表征。我们证明双电子-电子共振 (DEER) 光谱可以揭示来自受控 Suzuki-Miyaura 偶联聚合的低聚-（9,9-二辛基芴）中单个正聚体的链长分布和链构象和灵活性。所需的自旋标记链末端分别通过 TEMPO 取代的引发剂和链终止剂与原位催化剂体系有效地引入。通过逐步方法获得作为参考材料的单个精确链长低聚物。还可以在聚（芴）纳米粒子中访问链长度分布、链构象和灵活性。

  Oligofluorene blue emitters for cholesteric liquid crystal lasers

  摘要：

  We present the synthesis and characterization of an oligofluorene series whose chemical structure has been tuned to have amorphous nature, compatibility with liquid crystalline matrices and intrinsic chirality. Oligofluorenes are good blue emitters and the emission quantum yield is around 0.8 in the violet-blue range. The prepared materials are suitable for mirror-less laser applications based on a dye-doped liquid crystal resonator. We propose to use fluorene-based compounds to combine two necessary properties to achieve laser emission from cholesteric liquid crystal mixtures: chirality and luminescence. A good intensity emission and a fine tuning of the laser emission are demonstrated. (C) 2010 Elsevier B.V. All rights reserved.

  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

  Synthetic polymers are mixtures of chains with different lengths, and their chain length and chain conformation are often experimentally characterized by ensemble averages. We demonstrate that double electron-electron resonance (DEER) spectroscopy can reveal the chain length distribution and the chain conformation and flexibility of the individual n-mers in oligo-(9,9-dioctylfluorene) from controlled Suzuki-Miyaura
