项目摘要
The present research has been carried out to study the synthesis and property of novel polymer "poly[3]rotaxane" by using protocol of reversible covalent bond cleavage. A dumbbell molecule was designed as an axle component which contained two secondary ammonium moieties on it and two bulky groups at the termini, by using thiol-disulfide interchange reaction. A mixture of the dumbbell molecule and a isophthaloyl diamide possessing two dibenzo-24-crown-8-ether moieties was treated with a catalytic amount of benzenethiol to give 65% yield of poly[3]rotaxane with Mn 25000. The effects of the structures of the components, solvent, catalyst, and concentration on the polymerization were studied in detail. When the axle component having longer alkyl chain was employed, the polymerization was sluggish to require much longer reaction time (more than 1 week) to reach the equilibrium. However, the molecular weight of the resulting polymers were higher than that from shorter alkyl chain derivative, … More probably because of the suppression of the formation of 1:1 adduct of the two componets, i.e. the axle and wheel monomers.Thermal analyses and decomposition of poly[3]rotaxane were examined. Glass transition temperature and 5% weight loss temperature were 140℃ and 330℃, respectively, as determined by TGA and DSC analyses. Poly[3]rotaxane was treated with triohenylphosphine-water system as a typical reducing system for disulfide, and the corresponding reduced form of the dumbbell (a thiol) and the homofitopic crown ether (the wheel molecule) as the starting materials were recovered, suggesting the recycling property of poly[3]rotaxane.The synthetic method of poly[3]rotaxane was extended to the corresponding network polymer, polyrotaxane network. Poly(crown ether) was used instead of the homoditopic crown ether resulted in the formation of solvent-insoluble gel material which was well swelled in DMF by the reaction with the dumbbell molecule. The gelled polymer as polyrotaxane network was translucent when dried but transparent when swelled in DMF. The property of the elastic swelled gel was controllable by changing the conditions, monomer feed ratio, concentration, solvent and so on Less
本研究已经进行了研究,以研究新型聚合物“ poly [3]轮济烷”的合成和特性,并使用可逆的共价键裂解方案。通过使用硫醇 - 二硫化物的互换反应,将哑铃分子设计为轴成分,该轴分成分在术语上包含两个二级铵部分,术语中有两个笨重的基团。哑铃分子的混合物和同二酰二酰二酰胺具有两个二苯并-24-Crown-8-乙醚部分,用催化量的苯甲醇处理,可提供65%的poly [3] Rotaxane的收率[3] Rotaxane,并用MN 25,000。详细研究了组件,溶剂,催化剂和浓度对聚合的结构的影响。当使用具有较长烷基链的轴成分时,聚合迟钝,需要更长的反应时间(超过1周)才能达到等效物。然而,所得聚合物的分子量高于较短的烷基链衍生物的分子量,……更可能是因为抑制了两个组分的1:1加合物的形成,即轴和车轮单体。透射分析和poly [3] rotaxane的分析。通过TGA和DSC分析确定,玻璃过渡温度和5%的体重减轻温度分别为140℃和330℃。将二苯乙烷用三苯基膦 - 水系统处理为典型的二硫化物还原系统,以及相应的哑铃(硫醇)和相应的降低形式(硫醇)和同型冠状醚(车轮分子)(轮子分子),作为起始材料,作为旋转网络,表明了旋转的旋转态度[3]旋转型[3] contys ofdane。聚合物,Polyrotaxane网络。使用poly(冠状)代替同型牙冠醚,导致形成溶剂不溶的凝胶材料,该材料与与哑铃分子的反应在DMF中膨胀了。当在DMF中膨胀时干燥但透明时,胶凝聚合物作为polyrotaxane网络是半透明的。通过改变条件,单体进料比,浓度,溶剂等的条件,弹性膨胀凝胶的特性受到控制
