【摘要】 离子液体是由特定有机阳离子和阴离子构成的,在室温或近于室温下呈液态的离子体系。它具有熔点低,无明显蒸汽压,不易燃,不挥发和电化学窗口宽等优点,已经广泛应用于有机合成、催化、材料、化工、萃取分离以及金属电沉积等领域。但是目前对离子液体的结构认识尚处于初步阶段,还有许多问题需进一步研究。通过量子化学方法探索气相条件下离子液体离子对的稳定构型、相互作用等微观结构和光谱性质,从而模拟和预测液态下离子液体的结构和宏观实验性质之间的关系。对离子液体结构和性质的研究可以为人们进一步认识和应用离子液体提供充分、准确的数据,具有重要的科学意义．更多还原

【Abstract】 Ionic liquids which are liquids at ambient temperature,are completely composed of anions and cations.They have many attractive properties,such as such as low melting points,negligible vapor pressure,nonvolatile,nonflammable,wide electrochemical windows and have been widely and successfully applied many fileds such as organic synthesis,catalysts,materials,chemical engineering,extraction and electrodepostion of metals.Science the structural properties are the key points to understanding the thermodynamic,dynamic,and other properties of ionic liquids,it is very important to understand the structural properties of ionic liquids.更多还原
