Description

technical field [0001] The invention relates to the field of chemistry, in particular to a copper coordination polymer and its preparation method, crystal and application. Background technique [0002] Coordination polymers are structures in which inorganic or metal-organic polymers containing metal cation centers are connected by organic ligands. Coordination polymers are more formally referred to as having repeating coordinating entities extending in 1, 2 or 3 dimensions. [0003] The repeating units of coordination polymers are coordination complexes. Coordination polymers include subclasses of coordination networks that are extensions of coordination compounds, repeating through coordination entities in one dimension, and having two or more individual chains, rings, helical links or through Coordinating entities extend cross-links between coordinating compounds in 2 or 3 dimensions. The coordination networks generated by these void-containing organic ligands have the ...
