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 . |
