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] Application of 5-picoline tetrazole multidentate ligand [5-[5-methyl-2-pyridyl]tetrazolium] and organic bisphosphine ligand [N,N-bis[diphenylphosphoryl] Amines], designed and synthesized monovalent copper complexes, and applied them to stimuli-responsive light-emitting and color-changing materials, but there is no public report in the literature so far

Description

technical field [0001] The invention relates to the application of a 5-methylpyridine tetrazolium tetranuclear copper[I] complex in a stimulus-responsive luminescent color changing material, and belongs to the technical field of stimuli-responsive luminescent color changing new material synthesis. Background technique [0002] At present, due to the influence of strong spin-orbit coupling and heavy atom effect, metal luminescent complexes can theoretically utilize all singlet and triplet energies to improve luminescent quantum efficiency. 。 At present, the research on metal luminescent complexes mainly focuses on the transition metals of the fifth and sixth periods, especially the 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 lumine...
