extremely high ionicliquid concentrations, up to molar ranges in some cases. The biodegradability of these ionicliquids was assessed, and new biotechnological applications for them are proposed, e.g. as solvents for biopolymers. This study leads to the better understanding of the anion influence on the ionicliquid toxicity, but its core is the recognition that conscious design of ionicliquids can be used

Nonaqueous Lyotropic Ionic Liquid Crystals: Preparation, Characterization, and Application in Extraction
A class of new ionic liquid (IL)‐based nonaqueous lyotropic liquidcrystals (LLCs) and the development of an efficient IL extraction process based on LC chemistry are reported. The nonaqueous LLCs feature extraordinarily high extraction capacity, excellent separation selectivity, easy recovery, and biocompatibility. This work also demonstrates that the introduction of self‐assembled anisotropic nanostructures
据报道,一类新型的基于离子液体(IL)的非水溶致液晶(LLC)以及基于液相色谱化学技术的高效IL提取工艺的开发。非水LLCs具有极高的提取能力,出色的分离选择性,易于回收和生物相容性。这项工作还表明,将自组装的各向异性纳米结构引入IL系统是克服IL固有的强极性并增强IL分子识别能力的有效方法。在非常高的进料浓度(> 100 mg mL -1)下,具有氢键供体的有机化合物的基于IL的LLCs的分配系数达到了前所未有的50–60的值。),是普通IL,传统有机和聚合物萃取剂的800-1000倍。基于IL的非水LLC结合了IL和LC的独特特性,为开发高性能萃取方法开辟了一条新途径。
