Design and synthesis of new porous organic materials: Porous liquids

James等人在2007年提出了一种新型多孔材料的想法。这些被描述为“分子内具有明确孔隙的液体，能够识别其他物种的分子。”根据多孔液体的分子结构和是否存在溶剂分子，已经定义了几种多孔液体。多孔液体与传统液体不同，即使溶剂分子存在，孔隙也在分子内部，它们的空腔仍然是空的。这些材料的特性将使它们能够用于许多应用，例如气体分离和氢气储存。该项目将继承Copper等人的工作，他们从PCP中的多孔有机笼中合成了多孔液体。目前的系统存在几个问题，因为与类似的固体材料相比，孔隙率相对较低。五氯苯酚也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度提高至少50%来克服这些问题。为了做到这一点，将探索新的系统，特别是向多孔笼型离子液体的方向发展。O'Reilly， N., Giri， N.，和James， s.l.，多孔液体。化学。欧元。[j] . 2007, 13(3): 30 - 30。Giri， N., Del Pópolo, m.g., Melaugh， G., Greenaway。r.l.,Rätzke， K., Koschine， T.,Pison， L., Costa Gomes, m.f., Cooper, a.i.和James， s.l.。具有渗透孔隙度的液体。自然科学，2015,27(5):216-221。张J。,柴,S .

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.
