Abstract

The invention provides an application of a 3-methylpyridyl tetrazolate tetranuclear copper[I] complex in a stimulus-responsive luminescent color-changing material. The 3-methylpyridyl tetrazolate tetranuclear copper[I] complex luminescent color-changing material is a perchlorate.di[5-[3-methyl-2-pyridyl]terazolyl].tetra[N,N-bis[diphenylphosphoryl]amine]tetracopper[I] complex, and has a molecular formula of C110H96Cl2Cu4N14O8P8, and a molecular structure of the complex is shown in the specification. The complex belongs to novel stimulus-responsive luminescent color-changing materials and has good application prospects.

Description

technical field [0001] The invention relates to the application of a 3-picoline tetrazolium tetranuclear copper [I] complex stimulus-responsive light-emitting color-changing material, and belongs to the technical field of synthesis of new stimulus-responsive light-emitting 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 luminescen...
