纳米多孔分子晶体（NMCs）是由离散分子组成的纳米多孔材料，它们之间只存在非共价相互作用。它们不具有由共价键或配位键组成的扩展框架。它们是通过从包裹体化合物（ic）中去除客体分子形成的，对于大多数ic来说，这一过程通常会导致晶体开放结构的崩溃，但对于纳米mcs来说，宿主分子的包装被保留并获得纳米孔隙。近年来，通过气体吸附技术已经证实了一些纳米纤维素材料，本文对这些材料进行了综述。此外，还讨论了这些晶体稳定性的原因。作者认为，在剑桥结构数据库（Cambridge Structural Database， CSD）中可以很容易地找到更多的ic结构，它们可能是nmc的前体。
Nanoporous Molecular Crystals (NMCs) are nanoporous materials composed of discrete molecules between which there are only non-covalent interactions-i.e. they do not possess an extended framework composed of covalent or coordination bonds. They are formed from removing guest molecules from inclusion compounds (ICs) a process that for most ICs usually results in the collapse of the open structure of the crystals but in the case of NMCs the packing of the host molecules is retained and nanoporosity obtained. In recent years a number of NMCs have been confirmed by the technique of gas adsorption and these materials are surveyed in this feature article. In addition, the reasons for stability of these crystals are discussed. It is the author's belief that many more ICs, the structures of which are readily obtainable from the Cambridge Structural Database (CSD), may act as precursors to NMCs.
