  Aqueous-Biamphiphilic Ionic Liquid Systems: Self-Assembly and Synthesis of Gold Nanocrystals/Microplates

  摘要：

  Biamphiphilic ionic liquids (BAILs) based on 1,3-dialkylimidazolium cation and alkyl sulfate anions ([C(n)H(2n+1)mim][CmH2m+1OSO3]; n = 4, 6, or 8; m = 8, 12) have been synthesized and characterized for their self-assembling behavior in the aqueous medium. Effects of alteration of alkyl chain length in cation and anion on surfactant properties of BAILs have been examined from surface tension measurements. The effectiveness of surface tension reduction for BAILs has been found to be exceptionally higher as compared to single chain surface active ILs/conventional surfactants. The thermodynamics of the aggregation process has been studied using isothermal titration calorimetry (ITC) and temperature dependent conductivity experiments. Dynamic light scattering (DLS), nuclear magnetic resonance (NMR), and transmission electron microscopy (TEM) studies showed that BAILs formed distinct aggregated structures depending upon the amphiphilic character present in the cation and anion. BAILs ([C(n)H(2n+1)mim][CmH2m+1OSO3]) form micelles when n = 4, 6; m = 8, intermicellar aggregates when n = 4, 6; m = 12, and vesicles when n = 8; m = 8, 12. Gold nanoparticles and microplates have been synthesized in micellar and vesicle solutions of BAILs using a simple photoreduction method. The studies show the potential of BAILs for constructing micelles and supramolecular assemblies, such as bilayer vesicles, which are effective in preparation of nanomaterials of controlled size and morphology.

  concentration as well as the nature of BAILs. Different interactional phenomena such as the formation of ion-pair complexes, dimers, and solubilisation of monomers of MB have been observed in different concentration regimes of BAILs. A quantitative evaluation of the process of interaction between MB and BAILs has been made in terms of various micellar and binding parameters exploiting UV-visible absorption

  氧化还原活性染料亚甲基蓝（MB）与表面活性双亲性离子液体（BAIL）的相互作用：1-丁基-3-甲基咪唑十二烷基硫酸盐，[C 4 mim] [C 12 OSO 3 ]和1-己基-3-甲基咪唑十二烷基硫酸盐[C 6 mim] [C 12 OSO 3]已经在水性介质中进行了研究，以探索表面活性剂离子液体（ILs）在染料-表面活性剂化学领域的候选资格。各种热力学，光谱学和电化学技术，例如电导率，稳态荧光，紫外可见吸收和循环伏安法（CV）已用于获得有关MB-BAIL相互作用的全面信息。可以看到MB的存在会增强BAIL的临界胶束浓度（cmc）。MB和BAIL之间的相互作用程度随BAIL的浓度和性质而变化。在不同的BAIL浓度方案中，已观察到不同的相互作用现象，例如离子对络合物的形成，二聚体和MB单体的增溶。已经通过利用紫外可见吸收和CV测量对各种胶束和结合参数进行了MB和BAIL相互作用过程的定量评估。疏水性相对较高[C6个MIM]

  In continuation of our earlier investigations, this report presents a rationale behind the design of a series of imidazolium based ionic liquids and their biodegradation using the CO2 headspace test (ISO 14593 method, OECD 310). The effect on biodegradability of these salts through variation of the N-substituted side chains of imidazolium ions was examined further through incorporation of various functional groups and increased alkyl chain lengths. A series of anions containing moieties known to be biodegradable were also incorporated into a number of imidazolium based salts and examined in a similar fashion.

  本报告延续了我们之前的研究，介绍了一系列咪唑离子液体的设计原理，以及使用二氧化碳顶空试验（ISO 14593 方法，OECD 310）对其进行生物降解的情况。通过加入各种官能团和增加烷基链长度，进一步研究了咪唑离子 N 取代侧链的变化对这些盐类生物降解性的影响。一系列含有已知可生物降解分子的阴离子也被加入到一些咪唑盐中，并以类似的方式进行了研究。
