Description

technical field [0001] The invention relates to the technical field of organic coordination compounds, in particular to a one-dimensional silver cluster coordination polymer and its preparation method and application. Background technique [0002] In recent years, metal clusters / polymers have attracted extensive attention from scientists due to their novel structures and potential applications in the fields of catalysis, biomarkers, biosensing and luminescence. Among the metal clusters, the multifunctional silver clusters with unique structure and excellent performance are the research hotspots in the fields of chemistry and biology. On the other hand, the classification of OLED light-emitting materials can be divided into fluorescent light-emitting materials and phosphorescent light-emitting materials according to the light-emitting method. Among them, phosphorescent materials usually need to use the spin-orbit coupling of heavy metal atoms to make the recombination rate o...
