  Synthesis of new aryl and hetaryl dibromides and diiodides, the monomers for preparation of polyarylene ethynylenes

  摘要：

  Dibromides and diiodides with quinoxaline, phenylimidazole, and hexa- or pentaphenylarylene fragments were synthesized from dihalotolans obtained from chloral. Oligoarylene ethynylenes were synthesized by the reaction of the monomers with equimolar amounts of diethynyl aromatic compounds in the presence of the Pd-II complex. Oligomers with imidazole and hexa(penta)arylbenzene cycles are soluble in amide organic solvents and their reduced viscosities do not exceed 0.09 dL g(-1).

  The donor–acceptor system 4 having pyrazine scaffold as an acceptor moiety coupled to donor amino groups through rotatable phenyl rings has been synthesized, which formed aggregates in aqueous media, exhibited copper induced restriction to intramolecular rotation, and served as a “not quenched” probe for the detection of copper(II) ions. During this process, the aggregates of derivative 4 acted as

  合成了具有吡嗪骨架作为受体部分的供体-受体系统4，该受体部分通过可旋转的苯环与供体氨基连接，在水介质中形成聚集体，表现出铜诱导的分子内旋转限制，并用作“未淬灭”探针用于检测铜离子。在此过程中，衍生物4的聚集体充当生成CuO NP的反应器和稳定剂，它们自身被氧化形成多胺衍生物6。有趣的是，氧化物种6 与氧化铜纳米粒子结合使用时，可作为光收集天线，并在温和且环保的条件下（室温，水性介质，空气条件和可见光辐照）在Sonogashira偶联中表现出出色的光催化效率。

  Hexaphenylbenzene (HPB) derivatives 5 and 7 having rhodamine B moieties have been designed and synthesized, and have been shown to display solvent dependent. Fluorescence resonance energy transfer (FRET) and through bond energy transfer (TBET) in the presence of Hg2+ ions among the various cations (Cu2+, Pb2+, Zn2+, Ni2+, Cd2+, Ag+, Ba2+, Mg2+, K+, Na+, and Li+) have been tested. Derivative 5 displays quite high through bond energy transfer efficiency in the presence of Hg2+ ions in methanol whereas derivative 7 exhibits better FRET efficiency in the presence of Hg2+ ions in THF and CH3CN than derivative 5.

  Bundles of fibers of hexaphenylbenzene‐PEG derivatives in aqueous solutions are inferred from polarized and depolarized light scattering. The water uptake behavior and the self‐assembled structures can be controlled by changing the length of the PEG chains. With shorter PEG chains, the objects contain less water and the density of the self‐assembled structures is higher.

  从偏振光和去偏振光散射可以推断出水溶液中六苯基苯-PEG衍生物的纤维束。吸水行为和自组装结构可以通过改变PEG链的长度来控制。PEG链越短，物体所含水量就越少，自组装结构的密度也就越高。

  A Diels-Alder route to dendritic and hyperbranched polyphenylenes, based on hexa(penta)phenylbenzene units, is described. Using ethynyl-, propynyl- and phenylethynyl-substituted tetraphenylcyclopentadienones 1c−e, hyperbranched polymers with molecular weights Mw as high as 107,000 g mol−1 are obtained. The new dendritic polyphenylene 5c is synthesized starting from 3,3′,5,5′-tetraethynylbiphenyl (2c)
