本文以十二胺、丙烯酸甲酯和乙二胺為原料，通過邁克爾加成反應(yīng)和酰胺化縮合反應(yīng)，合成了一種一端具有長鏈烷基，另一端具有低支化結(jié)構(gòu)的超支化有機(jī)物R12-1.0G，通過元素分析、IR和NMR等手段對產(chǎn)物的結(jié)構(gòu)進(jìn)行了表征。同時將其與月桂酸進(jìn)行靜電力自組裝做為主體分子，以剛果紅為客體分子，研究了月桂酸與甲苯的質(zhì)量比、R12-1.0G濃度對染料相轉(zhuǎn)移行為的影響。結(jié)果表明：在月桂酸與甲苯的質(zhì)量比為1:2時，R12-1.0G對剛果紅的轉(zhuǎn)移率達(dá)到84.26%；隨著R12-1.0G濃度的增加，染料剛果紅的轉(zhuǎn)移率也隨之增大，這一實(shí)驗(yàn)結(jié)果與客體分子的化學(xué)結(jié)構(gòu)一定的關(guān)系。 （求高手棒棒忙，著急啊，專業(yè)一點(diǎn)就完美啦�。。。� |

| 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. |

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 . |
