Synthesis and Characterization of a Novel Azo Compound with 'Dumbbell Shape';

“哑铃状”偶氮化合物的合成与表征

The dumbbell-shape compounds, quaternary ammonium salts(3) of 4,4′-bipyridines bridged 2,2′-bipyridine in yields of about 90%, were synthesized by solid grinding at room temperature from quaternary ammonium salts(2) of N-substituted 4,4′-bipyridine which were prepared via the reaction of 4,4′-bipyridine and tosylate(or benzyl bromide) containing stopper in yields of 60%~90%.

采用室温固相研磨的方法,4,4′-联吡啶与连有阻塞基的乙氧乙醇磺酸酯(或苄溴)反应,得到单取代的4,4′-联吡啶六氟磷酸盐(2),2再与α,α′-二(溴甲基)-2,2′-联吡啶反应,得到哑铃型化合物——2,2′-联吡啶桥连的双-4,4′-联吡啶六氟磷酸盐(3),收率约90%。

Molecular shuttle locate foreland research field in organic chemistry, they are composed of one cyclic compound and a dumbbell-shaped compound.

哑铃型化合物作为构筑轮烷和分子梭的关键砌块,本文综述了现在所报道的含4,4’-联吡啶哑铃型化合物的类型和合成方法,4,4’-联吡啶的成盐反应一般是以无水乙腈为溶剂,加热回流数天,产率很低,同时有副产物产生,产物的分离、纯化困难。

This approach was used to simulate plane Couette flows of dilute polymeric fluids by the FENE dumbbell mode.

采用确定性方法数值求解了聚合物稀溶液的微观-宏观模型,其中,宏观尺度上用有限体积法求解守恒方程,介观尺度上用谱方法求解Fokker-Planck方程和聚合物对偏应力张量的贡献,模拟了聚合物稀溶液FENE哑铃模型的平板Couette流动,给出了速度随时间变化的剖面图,分析了移动平板速度、哑铃的量纲1有限拉伸参数和Deborah数对流动的影响,同时也验证了有限体积法与谱方法结合求解聚合物微观-宏观模型的有效性。
