Title POROUS COORDINATION POLYMER AND APPLICATION THEREFOR
Abstract The present invention addresses the problem of providing a novel porous coordination polymer having super water-repellent properties. The present invention relates to a porous coordination polymer including a divalent or trivalent metal ion and an organic ligand represented by general formula (1) (In formula (1), X1, X2, and X3 are the same or different, and represent CO2 -, CS2 -, PO3 2-, PO4 2-, AsO3 2-, AsO4 2-, SO3 -, SO4 -, SeO3 -, SeO4 -, TeO3 -, or TeO4 -. R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, R11, and R12 are the same or different, and represent hydrogen atoms or C1-20 alkyl groups.), the metal ion and the organic ligand being coordinate bonded in alternating fashion.
Outline of related art and contending technology BACKGROUND ART
A water-repelling surface not scientific definition, in general, the surface water-repelling, water contact angle or more 150°, refers to a very hard to be wet with water surface. In general, as a main component fluorine solid surface made of a material having low surface energy by, it is known that the excellent water repellent and, appropriate roughness and over a surface is by applying a (clutter), to enhance the water repellency is known.
On the other hand, solid compound having the structure of the pores within the porous referred to as the compound. The porous material may be organic, inorganic and other devices are known and, as a typical example, zeolite, activated carbon, silica gel, molecular sieves and the like. In recent years, a new porous material, porous coordination polymer (porous coordination polymer, PCP) is attracted attention. Is a porous coordination polymer, the metal ion and the organic ligand coordination using the material and the porous structure, the gas storage or separation, catalyst or the like are expected to be applied to. However, the porous coordination polymer is one known in the art, low in their stability toward water, tends to degrade water exposure, is limited to a practical use.
Therefore, the porous coordination polymer in water in order to improve the stability of, the surface of the porous coordination polymer to the water repellency (ultra) have been attempted. The non-patent document 1, a fluorinated aromatic ring is an organic ligand PCP, to achieve a contact angle 151 ± 1° described. Non-patent document 2 and 3 is, at the end of a compound having a bulky alkyl chain and is an organic ligand PCP, achieved a contact angle greater than 150° described.
