1-D tubular alkali metal-organic framework materials and synthesis method thereof

摘要

PURPOSE: A method for preparing alkali metal-organic framework compound of one dimensional is provided to improve vapor absorption or long-term storage ability. CONSTITUTION: A metal-organic framework compound comprises infinite one dimensional band having two AO_6 chains and one AO_8 chain; and a channel structure containing benzentricarboxylic acid linker. A is alkali metal. The metal organic framework compound is denoted by chemical formula 1 (A_3C_6H_3(CO_2)(CO_2H_0.5)(CO_2H)_2). A method for preparing the compound of chemical formula 1 comprises: a step of contacting tricarboxylic linkers and alkali metal precursor under the presence of a solvent for solvothermal reaction; and a step of obtaining a crystal from the reactant. The solvent is HCON(CH_3)_2.
