苯偶酰

This reaction was further extended to the coupling reaction of amide with diiodo biphenyl; and the carbazole derivatives were synthesized in 53%-95% yield.

另外将该反应体系的底物进行了进一步的拓展，用酰胺和二碘代联苯化合物偶联，合成了9个咔唑衍生物，收率在53％—95％之间，并运用~1H NMR、~(13)C NMR、HRMS等分析测试手段对这些化合物进行了表征。

The packing arrangements in their mesophases of the polymers were influenced by the end functional group obviously. All the polymers with amide-substituted group showed the partly interdigitated bilayer smectic phase structure.

另外，聚合物的热行为和相转变行为受液晶聚合物的末端键接基团影响显著，所有末端包含酰胺基团的侧链偶氮苯聚合物在液晶温度均形成了部分穿插的双层近晶相结构。

RESULTS Specific inhibitors of respiratory chain complexes Ⅰ,Ⅱ,Ⅲ, and Ⅳ of rotenone, thenoyltrifluoroacetone, antimycin A and potassium cyanide, and the mitochondrial uncoupler carbonyl cyanide mchlorophenylhydrazone resulted in obvious changes of intracellular ROS production.

结果 呼吸链复合物Ⅰ，Ⅱ，Ⅲ，和Ⅳ抑制剂鱼藤酮、噻吩甲酰三氟丙酮、抗霉素A、氰化钾及氧化磷酸化解偶联剂羰氰苯腙能够明显改变But所致细胞内活性氧的产生。

EVA/LDPE/ CB conductive foam was made of EVA and LDPE as matrix,HG-1P CB and ACET CB as conductive filler,AC as foamer and DCP as crosslinker.

文章以乙烯-乙酸乙烯酯和低密度聚乙烯为主基体，特导炭黑(HG-1P)和乙炔炭黑为导电填料，偶氮二甲酰胺为发泡剂，过氧化二异丙苯为交联剂，制备了EVA/LDPE/炭黑导电泡沫复合材料。

A new monomer,4-hexanoxyl-4′-undecylene-[10]-acyloxyazobenzene was synthesized using the main materials:phenol,underlenic acid,1-bromo- n -hexane, p -nitrophenol,thionyl chloride,by the substitution,reduction,couping and diazotization methods.A new polymer was prepared by hydrosilation reaction of poly (methylhy-drosiloxane) with the monomer.

以苯酚、十一烯酸、正溴己烷、对硝基苯酚和二氯亚砜为主要原料，通过取代、还原、重氮化和偶合等反应，合成了一种新的液晶单体 4-己氧基-4′-十一烯-[10]-酰氧基偶氮苯，并与聚通过硅氢加成生成一种新的高分子液晶。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
