本文以十二胺、丙烯酸甲酯和乙二胺为原料，通过迈克尔加成反应和酰胺化缩合反应，合成了一种一端具有长链烷基，另一端具有低支化结构的超支化有机物R12-1.0G，通过元素分析、IR和NMR等手段对产物的结构进行了表征。同时将其与月桂酸进行静电力自组装做为主体分子，以刚果红为客体分子，研究了月桂酸与甲苯的质量比、R12-1.0G浓度对染料相转移行为的影响。结果表明：在月桂酸与甲苯的质量比为1:2时，R12-1.0G对刚果红的转移率达到84.26%；随着R12-1.0G浓度的增加，染料刚果红的转移率也随之增大，这一实验结果与客体分子的化学结构一定的关系。 （求高手棒棒忙，着急啊，专业一点就完美啦！！！） |

the experiment took Dodecylamine ,Methacrylate and Ethylenediamine as the reactants , through Michael Addition and Amidation Condensation reaction to create (synthesize) a compound of R12--1.0G ,which having a long-chain alkyl at the one side end and the other side end being a hyperbranched organic compound characterized by low-branching structure . R12-1.0G compositional structure is identified by a series of analytical methods like elemental analyses , IR and NMR ,etc. . At the same time , in order to research the mass ratio between Lauric acid and Toluene , and the conducting effects of R12-1.0 G concentration on the phase-transferring of dyes , the R12-10.0 G ,through electrostatic ion self-assembling with Lauric acid , is as the hosting molecules while Congo Red is as the guesting molecules. the results showed the mass ratio between Lauric acid and Toluene is at 2:1 , the transfer-rate of R12-1.0G against Congo Red reached 84.26% . In addition , with the concentration of R12-1.0G increasing , the transfer-rate Congo Red is also growing . the experiment indicated that the results of transfer-rate is being connected to the chemical structure of the guesting molecules . |

| This paper describes 12 amine, methacrylate and ethylenediamine as raw material, by Michael addition and amidated condensation reaction, a side has long alkyl, on the other end has a low branched structure hyperbranched organic R12-1.0G, elemental analysis, IR and NMR, etc. means on the product structure characterization. At the same time it with lauric acid for electrostatic force self-Assembly as a principal molecules to Congo red as guest molecules of lauric acid and toluene quality than, R12-1.0G concentration on dye phase transition behavior. Results indicate that in lauric acid and toluene quality ratio of 1: 2, R12-1.0G of Congo red transfer rate of 84.26%; as the R12-1.0G concentration increases, dye transfer of Congo red ratio increases, this experimental results and guest molecules of chemical structure. |
