摘要
非多孔自适应晶体(nonporous adaptive crystals,英文简称为"NACs",中文简称为"纳客")是本课题组首次提出和定义的一种新颖的吸附和分离材料.基于柱芳烃的纳客具有易于制备,化学、水汽、热稳定性好,溶液加工性好,重复利用性高等优点,对科学研究产生了重要影响,并在化工行业具有潜在的应用价值.本文主要介绍基于柱芳烃的纳客在吸附和分离中的应用,讨论在吸附分离过程中所伴随的晶体结构由最初的非多孔晶体状态转变为新的包裹客体晶体状态以及单晶X射线衍射、粉末X射线衍射、气相色谱和核磁等实验方法用于研究晶体在吸附和分离过程中所产生的结构变化与吸附分离性能.这些机理的研究为基于柱芳烃的纳客在工业上的可能应用奠定了理论基础.
This review describes a novel kind of materials for adsorption and separation, nonporous adaptive crystals(NACs), which are firstly mentioned and defined by us. Compared with traditional porous materials, NACs of pillararenes can be synthesized easily, have good chemical, humid and thermal stabilities, are soluble in many common organic solvents, and can be reused many times. Here, we focus on the discussion of pillararene-based NACs for adsorption and separation and the crystal structure transformations from the initial nonporous crystalline state to new guest-loaded structures during the adsorption and separation processes. Single-crystal X-ray diffraction, powder X-ray diffraction, gas chromatography and solution NMR are the main techniques to investigate the adsorption and separation processes and the structural transformations. It is expected that this kind of materials will show practical applications in the chemical industry.
