METAL-ORGANIC MATERIALS AND METHOD FOR PREPARATION

摘要

The present invention provides metal-organic materials, more specifically organometallic polymers, comprising polypyridyl organic ligands such as tetrakis(4-(pyridin-4-ylethynyl)phenyl)methane, tetrakis(4-(2-(pyridin-4-yl)vinyl)phenyl)methane,3,5,7-tetrakis(4-(pyridin-4-ylethynyl)phenyl)adamantane or 1,3,5,7-tetrakis(4-(2-(pyridine-4-yl)vinyl)phenyl)adamantine, and metal ions structurally coordinated with said ligands, and having three-dimensional crystalline micro or sub-micro structure; as well as a method for the preparation thereof. These metal-organic materials are useful as adsorbents in processes for gas adsorption or separation.

1. A metal-organic material having a three-dimensional (3D) crystalline micro or sub-micro structure, comprising at least two ligands, at least two metal ions structurally coordinated with said ligands, and counter anions, wherein each one of the ligands is of the general formula I:
R1(R2—R3—R4)4,  I wherein R1 is C or adamantane-1,3,5,7-tetrayl; R2 and R3 each independently is absent, or selected from (C1-C8)alkylene, (C2-C8)alkenylene, (C2-C8)alkynylene, cycloalkylene, heterocycloalkylene, arylene-diyl, heteroarylene-diyl, or —N═N—, wherein said alkylene, alkenylene, alkynylene, cycloalkylene, heterocycloalkylene, arylene-diyl and heteroarylene-diyl may optionally be substituted with one or more groups each independently selected from halogen, —OR6, —CN, —COR6, —COOR6, —CON(R6)2, —OCOOR6, —OCON(R6)2, —(C1-C4)alkyl, —O—(C1-C4)alkyl, —(C1-C4)alkylene-COOR6, —N(R6)2, —NO2, —SR6, —SO2R6, or —S(═O)R6, or said alkylene, alkenylene and alkynylene may optionally be interrupted by one or more identical or different heteroatoms selected from S, O or N, and/or at least one group selected from —N═N—, —NH—CO—, —CO—NH—, —N(C1-C4alkyl)-, —N(C6-C10aryl)-, or —(C6-C10)arylene-diyl-, wherein R6 each independently is H, (C1-C4)alkyl, (C2-C4)alkenyl or (C2-C4)alkynyl; R4 each independently is a pyridyl of the formula II, 2,2′-bipyridyl of the formula III, or 2,2′:6′,2″-terpyridyl of the formula IV, linked through a carbon atom thereof; and R5 each independently is H, —COOH, —CN, —OH, or —NH2.
