甲氧苯胺

In this dissertation, two derivatives of aniline containing polyoxyethylene substituent m-phenylene diamino formyl alkylenediamine poly acetate and poly-3-aminobenzoate were designed and synthesized. And then, comb-shaped polyaniline grafted by PEO were prepared by chemical oxidation copolymerization. The structure of copolymers were characterized by FTIR, ultraviolet-visible spectrum, elemental analysis and TEM etc..

本文在设计并合成两种含聚氧乙烯取代基的苯胺衍生物——间苯二氨基甲酰己二氨基甲酸聚氧乙烯乙酸酯和3-聚氧化乙烯单甲醚基苯胺的基础上，采用化学氧化法将它们与苯胺进行共聚，制备出了聚氧乙烯接枝聚苯胺的梳型共聚物。

It was found that the introduction of t-butyl or methoxy group in the triphenylamine subunit could lead to more efficient photoinduced intramolecular charge transfer, thus improving the overall photoelectric conversion efficiency of the resultant DSSC.

研究结果表明叔丁基或甲氧基取代三苯胺基团能够促进分子内电子转移，进而提高染料分子的敏化效率。

All of the tripodal schiff base ligands and their complexes were characterized.

以三乙醇胺、巯基苯胺、巯基乙胺为初始原料，设计合成了六个三脚架结构的化合物，其合成路线如下：三乙醇胺与氯化亚砜反应得到三(2-氯乙基)胺(1)，然后与巯基苯胺或巯基乙胺在碱性条件下反应生成三脚架结构的三{[2-(2-氨基苯基)硫代]乙基}胺(2)或三{[2-(2-氨基乙基)硫代]乙基}胺(3)，然后再与水杨醛、2-甲酰基-8-羟基喹啉(8)、2-甲酰基-8-苄氧基喹啉(7)反应得到六种新型的含硫西佛碱化合

Optimum conditions are as follows: DMF is used as solvent, compound quaternary ammonium salt as catalyst, n(p-nitrochloro benzene):n=1: 1.2, m:m(p-nitrochloro benzene)=4%, m:m(p-nitrochloro benzene)1:1, and reacted under 155~160℃ for 18 h; reduction reaction is carried out in methanol with Raney nickel, which is used as catalyst; the raw product is added an antioxidant, and distilled simply under reduced pressure to obtain 4-fluoroaniline with excellence quality, purity is over 99.5%, total yield is 89.3%.

实验结果表明，氟化反应的最佳条件为：二甲基甲酰胺为溶剂、复合季铵盐为催化剂，n：n=1：1.2，m（催化剂：m=4%，m：m=1：1，于155~160℃下反应18h；还原反应在甲醇中进行，以阮内镍为催化剂；粗产品加入抗氧剂，减压条件下简单蒸馏得高品位的对氟苯胺。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.
