  Influence of self-assembly of amphiphilic imidazolium ionic liquids on their host–guest complexes with cucurbit[n]urils

  摘要：

  Two symmetric amphiphilic imidazolium ionic liquids having omega-undecenyl chains form supramolecular complexes with CB[7] and CB[8] in water as revealed by H-1 NMR spectroscopy and MALDI-MS. Binding constants in the range 10(4) to 10(5) M-1 were estimated from the conductivity measurements for the 1:1 complexes of these imidazolium ionic liquids with CB[7] and CB[8]. Radical initiated polymerization of these host-guest complexes at concentrations above the critical self-assembly concentration of imidazolium ionic liquids to form liposomes, destroys completely (CB[7]) or partially (CB[8]) the host-guest ionic liquid@CB[n] complex; this behaviour was proved by titration with acridine orange tricyclic dye, of CB[n]s in the colloidal solutions of the liposomes before and after performing dialysis to remove free CB [n]s. Thus, the increase in the fluorescence emission of acridine orange by CB[7] is not observed if the polymerized ionic liquid@CB[7] complex is submitted to dialysis to remove uncomplexed CB[7]. Analogous study by titration of absorbance change of acridine orange solutions caused by CB[8], reveals only a partial destruction of the host-guest complex by self-assembly of amphiphilic ionic liquid above the critical self-assembly concentration. The results obtained have been rationalized considering that the driving force for the formation of supramolecular ionic liquid@CB[n] complexes is a hydrophobic interaction between the apolar alkenyl chain and the cucurbituril interior cavity and that these hydrophobic interactions are disturbed when self-assembly leading to liposomes occurs.

  通过咪唑鎓离子液体的聚合形成脂质体：用作金催化酒精氧化的微反应器

  摘要：

  两足离子液体N，N'-双（10-十一碳烯基）-2-甲基咪唑在水性介质中与过硫酸钾聚合形成亚微米级脂质体。TEM研究表明，脂质体是聚合物颗粒几次形态转变的结果。在室温下光聚合导致球形颗粒具有一些内部空隙和聚合物链。我们利用了咪唑环上的正电荷，并使用光固化剂从咪唑单体和NaAuCl 4开始一步形成球形聚合物颗粒，其内部含有金纳米颗粒（10–15 nm）。发现该系统促进2-羟基苯甲醇选择性好氧氧化为水杨醛。
