中文摘要：

熔点是界定、研究离子液体及其使用过程的一个重要参考指标，因此研究离子液体分子结构与熔点之间的构效关系及其基本规律有特别重要的意义。本文以从近两百遍文献及Beilstein Gmelin网络数据库中收集的约900种咪唑类离子液体中的384种咪唑类离子液体的熔点数据为依据，考察了离子液体分子结构与熔点之间的构效关系及其基本规律，这对离子液体的设计合成及应用有指导作用。

英文摘要：

Melting point is an important parameter of ionic liquid, so there is great meaning to study the structureactivity relationship and essential rule of the molecular structure and melting point of ionic liquid. In this article, the data of melting point of 384 imidazolium ionic liquids were collected from Beilstein Gmelin database and about 200 literatures. According to these data, the structure-activity relationship and essential rule of the molecular structure and melting point of ionic liquid were studied. This is meaningful to the synthesis and application of ionic liquid.
