James et al. proposed the idea of a novel class of porous materials in 2007. These were described as 'liquids with well-defined pores within the molecular capable of molecular recognition of other species.'1 Several classes of porous liquids have been defined based on their molecular structure and whether solvent molecules are present. Porous liquids are unlike conventional liquids as their cavities remain empty even if solvent molecules are present and the pores are within the molecules themselves. The properties of these materials would allow them to be used in a number of applications, such as gas separation and hydrogen storage. The project will follow on from the work by Copper et al. who synthesised a porous liquid from porous organic cages in PCP. There are several problems with the current system as there was relatively low porosity compared to similar solid materials. PCP is also an expensive and toxic solvent so not ideal for large scale use. The aim of the project is to overcome these issues by improving porosity by at least 50%. New systems will be explored in order to do this, particularly moving towards porous cage ionic liquids. O'Reilly, N., Giri, N., and James, S.L., Porous Liquids. Chem. Eur.

James等人在2007年提出了一类新型多孔材料的想法。这些被描述为“分子内具有明确孔的液体，能够识别其他物种的分子。根据其分子结构和是否存在溶剂分子，已经定义了几类多孔液体。多孔液体与常规液体不同，因为即使存在溶剂分子并且孔在分子本身内，它们的空腔也保持为空。这些材料的特性将使它们能够用于许多应用，例如气体分离和储氢。该项目将延续Copper等人的工作，Copper等人利用五氯苯酚中的多孔有机笼合成了一种多孔液体。当前系统存在几个问题，因为与类似的固体材料相比，其孔隙率相对较低。五氯苯酚还是一种昂贵且有毒的溶剂，因此不适合大规模使用。该项目的目标是通过将孔隙率提高至少50%来克服这些问题。为了做到这一点，将探索新的系统，特别是朝着多孔笼离子液体的方向发展。O'Reilly，N.吉里，纽约，和詹姆斯，S.L.，多孔液体。欧洲化学品J. 2007，13，3020 - 3025.
