COORDINATION POLYMER CRYSTAL WITH POROUS METAL-ORGANIC FRAMEWORKS AND PREPERATION METHOD THEREOF

摘要

A coordination polymer crystal with a porous metal-organic framework is provided to store a larger amount of the guest molecules continuously by additionally chemically bonding an added material such as an organic compound, a metal cluster, or an organometallic compound to the coordination polymer crystal, thereby adjusting pore size and preventing separation of stored guest molecules at the same time, and a preparation method of the coordination polymer crystal is provided. In a coordination polymer crystal with a porous metal-organic framework, the coordination polymer crystal is characterized in that an added material selected from the group consisting of an organic compound, a metal cluster, and an organometallic compound is additionally chemical bonded to the crystal in a state that the crystal is maintained. The chemical bonding is covalent bonding, coordination bonding, or chemical adsorption. The added material has one or more bonding parts that can be chemically bonded to the coordination polymer crystal, and only one bonding part in the bonding parts of the added material is chemically bonded to the coordination polymer crystal in a way that the added material is grafted to the coordination polymer crystal. The added material has two or more bonding parts that can be chemically bonded to the coordination polymer crystal, and at least two bonding parts in the bonding parts of the added material is chemically bonded to the coordination polymer crystal at the same time in a way that the added material forms a cross-linkage in the coordination polymer crystal.
