Problems solved by technology

However, there are few literature reports on the construction of luminescent and color-changing materials based on monovalent copper complexes using nitrogen heterocyclic multidentate ligands and organic bisphosphine ligands, especially the stimulus-responsive luminescent color-changing materials based on monovalent copper complexes.
[0005] Using the pyridine tetrazole multidentate ligand [5-[2-pyridyl]tetrazolium] and the organic bisphosphine ligand [N,N-bis[diphenylphosphoryl]amide], a monovalent copper complex was designed and synthesized substances, and applied to stimuli-responsive luminescent color-changing materials, there is no public report in the literature

Description

technical field [0001] The invention relates to the application of a pyridine tetrazolium tetranuclear copper [I] complex in a stimulus-responsive luminescent and color-changing material, and belongs to the technical field of synthesis of new stimulus-responsive luminescent and color-changing materials. Background technique [0002] At present, due to the influence of strong spin-orbit coupling and heavy atom effects, metal luminescent complexes can theoretically use all singlet and triplet energies to improve the quantum efficiency of luminescence. At present, the research on metallluminescent complexes mainly focuses on transition metals of the fifth and sixth periods, especially transition metals of group VIII, such as ruthenium, osmium, iridium, and platinum. However, the transition metals of the fifth and sixth periods (except for a few metals of the first and second subgroups) are scarce in the earth's crust and are difficult to mine. Therefore, the cost of using lumin...
