Abstract

The invention relates to a copper coordination polymer as well as a preparation method and application of the copper coordination polymer. The copper coordination polymer is a nano-hole-containing Cu (II)-anthracenecyclo bistriazole two-dimensional coordination polymer having ion exchange and solvent exchange functions and is a complex having the following chemical formula, namely, {[Cu(tatrz)2(H2O)2](BF4)2} (1), wherein tatrz is 1-[9-(1H-1,2,4-triazole-1-yl) anthranyl-10-yl]-1H-1,2,4-triazole. When NaClO4 is added into aqueous and methanol solutions of the complex, ClO4<-> can replace BF4<-> in holes to obtain the complex {[Cu(tatrz)2(H2O)2](ClO4)2.5.56H2O} (1a). When the complex (1) is immersed in a mixed solvent of water and methanol of NaF, ClO4<-> cannot be replaced by F<->, which indicates that the complex has selective ion exchange property and has great application value in the field of material science.

Description

[0001] The present invention has been funded by the National Natural Science Foundation of China (21471113), the Tianjin Municipal Education Commission project (20140506), the Tianjin Normal University academic innovation promotion project for young and middle-aged teachers, and the Tianjin Higher Education Innovation Team Training Program (TD12-5038). technical field [0002] The present invention relates to a transition metal coordination polymer, especially a copper coordination polymer and its preparation method and application. The copper coordination polymer is Cu(II)-anthracycline bistriazole di Dimensional copper coordination polymer with selective ion exchange function. Background technique [0003] In recent years, the construction of materials with new open pore structures and capable of ion exchange and solvent adsorption is the most challenging subject. Not only because of their novel topology, but also because they often exhibit specific optical, electrical, ma...
