Description

technical field [0001] The invention belongs to the technical field of organic synthesis, and more specifically relates to a novel triazole fluorescent coordination polymer and its preparation method and application. Background technique [0002] The fluorescence effect refers to the phenomenon that the fluorescent substance emits light in the long-wave band after short-wave ultraviolet rays irradiate the fluorescent substance. Fluorescent materials are an important class of optoelectronic materials, which have a wide range of applications in the fields of biology, chemistry, information and materials due to their special light-emitting mechanism, and are an important carrier of high-tech research. [0003] Fluorescent materials include inorganic fluorescent materials and organic fluorescent materials. Rare earths, organic small molecules or polymers are usually used as raw materials to prepare fluorescent materials. These raw materials are expensive, which leads to high syn...
