近年来，离子液体的设计性推动了其在物理化学领域的无数领域的探索和开发。在相当程度上，人们对这些流体的极大关注归因于它们固有的设计者性质。然而，以详尽或有意义的方式强调这一重要方面的审查实例相对较少。在这篇重要的综述中，我们系统地综述了醚类和醇类官能化离子液体的集体文库的物理化学性质，重点介绍了离子结构对粘度、相行为/转变、密度、热稳定性、电化学性质和极性(如亲水性、氢键能力)等特征的影响。在本综述的后半部分，我们重点介绍了这些功能化离子液体在一系列学科中吸引人的应用，包括用作电化学的电解液或功能流体、萃取、两相体系、气体分离、碳捕获、碳水化合物溶解(特别是(Ligno)纤维素酶)、聚合物化学、抗微生物和抗静电剂、有机合成、生物分子稳定和活化以及纳米科学。最后，本文讨论了阴离子功能化的ILS，包括硫和氧功能化的类似物，以及胆碱基深度共熔溶剂(DESS)，这是一类新兴的流体，可以敏感地归类为IL的半分子近亲。最后，根据最近的报道，讨论了醚基和醇基ILS的毒性和生物降解性，并进行了谨慎的评估。通过仔细总结到目前为止有关含氧官能团设计者ILS的性质和应用的文献实例，我们的意图是，这篇综述为衡量该领域未来的进展提供了一个晴雨表，并引发了对这些看似取之不尽的液体的进一步思考--相对于它们的潜力--几乎没有接触过。非常清楚的是，这些非凡的流体材料将继续存在，就像某些设计规则正在慢慢开始出现一样。然而，公平地说，偶然也仍然发挥着不可否认的作用，突显了扩大计算机研究和灯塔的必要性，以吸引聪明的年轻研究人员进入该领域。
In recent years, the designer nature of ionic liquids (ILs) has driven their exploration and exploitation in countless fields among the physical and chemical sciences. A fair measure of the tremendous attention placed on these fluids has been attributed to their inherent designer nature. And yet, there are relatively few examples of reviews which emphasize this vital aspect in an exhaustive or meaningful way. In this critical review, we systematically survey the physicochemical properties of the collective library of ether- and alcohol-functionalized ILs, highlighting the impact of ionic structure on features such as viscosity, phase behavior/transitions, density, thermostability, electrochemical properties, and polarity (e.g., hydrophilicity, hydrogen bonding capability). In the latter portions of this review, we emphasize the attractive applications of these functionalized ILs across a range of disciplines, including their use as electrolytes or functional fluids for electrochemistry, extractions, biphasic systems, gas separations, carbon capture, carbohydrate dissolution (particularly, the (ligno)celluloses), polymer chemistry, antimicrobial and antielectrostatic agents, organic synthesis, biomolecular stabilization and activation, and nanoscience. Finally, this review discusses anion-functionalized ILs, including sulfur- and oxygen-functionalized analogs, as well as choline-based deep eutectic solvents (DESs), an emerging class of fluids which can be sensibly categorized as semi-molecular cousins to the IL. Finally, the toxicity and biodegradability of ether- and alcohol-functionalized ILs are discussed and cautiously evaluated in light of recent reports. By carefully summarizing literature examples on the properties and applications of oxy-functional designer ILs up till now, it is our intent that this review offer a barometer for gauging future advances in the field as well as a trigger to spur further contemplation of these seemingly inexhaustible and—relative to their potential—virtually untouched fluids. It is abundantly clear that these remarkable fluidic materials are here to stay, just as certain design rules are slowly beginning to emerge. However, in fairness, serendipity also still plays an undeniable role, highlighting the need for both expanded in silico studies and a beacon to attract bright, young researchers to the field.
