Description

technical field [0001] The invention relates to a preparation of Cu(II) coordination polymer and its preparation method, as well as Cu(I) coordination polymer prepared by using it and the method. Background technique [0002] Metal-organic coordination polymers have attracted widespread attention due to their potential applications in many fields such as luminescence, gas storage and catalysis. Due to the application potential of SCSC reaction in the field of material science, more and more people pay attention to the research of SCSC reaction. The reason why people are becoming more and more interested in studying SCSC reactions is that they can analyze and study the solid-state reaction mechanism. Through the method of single crystal diffraction, people can more directly observe the changes in the crystal structure during the reaction process. Unlike other solid-state reactions, single crystals maintain their integrity, including shape and transparency, during crystal tra...
