  共轭聚合物在主链上带有咔唑，芴和亚乙基二氧噻吩并带有氰基侧基：合成，光物理和电化学研究

  摘要：

  经由Sonogashira偶联聚合反应，已经设计并合成了六种新的共轭聚合物，这些聚合物沿着主链具有由咔唑，芴和亚乙基二氧噻吩（EDOT）部分组成，并且侧基带有连接到乙烯部分的氰基。光学和电化学表征表明，能带隙在2.35–2.44 eV范围内。此外，咔唑和EDOT的存在使这些聚合物成为更好的空穴传输材料，这可从循环伏安图中的低氧化电位峰（0.55-1.11 V）反映出来。此外，与原始THF相比，在90:10 THF /水混合物中，聚集增强发射（AEE）现象导致荧光强度增加了2.6倍。通过DLS（动态光散射）实验和SEM（扫描电子显微镜）研究进一步验证了AEE特性。溶液中以及聚苯乙烯基质中的聚合物在绿色区域发射（溶液状态Φ下的量子产率）f = 41–43％）的CIE值（0.25–0.36、0.52-0.57）。新型聚合物具有出色的热稳定性。©2016 Wiley Periodicals，Inc

  Two novel polymers containing triple bonds in the backbone with different conjugation types (acceptor–acceptor and acceptor–donor structures) were synthesized and investigated for their crosslinking characteristics under UV irradiation. The crosslink formation was proven via UV-vis and IR spectroscopy, and it was found that the crosslinked polymers have solvent resistance properties during subsequent

  A new bead type and diallyl-POSS based polyfluorene (P2) with high symmetrical structure was synthesized via Heck coupling reaction between oligomeric alkynyl fluorene (P1) and diallyl polyhedral oligomeric silsesquioxanes (diallyl-POSS). The molecular weight and the conjugated length of P1 and P2 were well controlled to acquire good solubility and excellent optical property. The bead-type POSS based polymer was characterized by gel permeation chromatography (GPC), FT-IR, H-1 NMR and photo-luminescence (PL) spectra. High Resolution Transmission Electron Microscopy (HRTEM) micrographs showed that diallyl-POSS were uniformly nano-dispersed in the polymer matrix. Compared with P1, the POSS based polyfluorene P2 exhibited not only a higher thermal stability, but also an improved photophysical property in solution and solid states. The incorporation of diallyl-POSS resulted effectively in inhibiting the strong stacking/dipole-dipole interaction between fluorescent groups in the polyfluorene. The experimental results indicate that the bi-functional FOSS based light-emitting polymers with high symmetrical structure can have great potential in optical materials and devices, such as OPV or PLED, etc. (C) 2014 Elsevier Ltd.

  The synthesis, structural, and photophysical characterization of a series of new fluorescent donor acceptor and acceptor-acceptor molecules, based on the fluorenyl ring system, with two-photon absorbing properties is described. These new compounds exhibited large Stokes shifts, high fluorescence quantum yields, and significantly, high two-photon absorption cross sections, making them well suited for two-photon fluorescence microscopy imaging. Confocal and two-photon fluorescence microscopy imaging of COS-7 and HCT 116 cells incubated with probe I showed endosomal selectivity, demonstrating the potential of this class of fluorescent probes in multiphoton fluorescence microscopy.
