Abstract

The invention relates to a synthesis technique of a new luminescent material, and in particular relates to a copper [I] binuclear complex luminescent material containing a trifluoromethylpyrimidine triazole bi-chelated ligand and a preparation method thereof. The trifluoromethylpyrimidine triazole bi-chelated ligand (5-trifluoromethyl-3-[2-pyrimidinyl]-1 hydro-1,2,4-triazole [fpmtzH for short]) and an organic phosphine auxiliary ligand (triphenylphosphine[PPh3 for short]) are applied to prepare the trifluoromethylpyrimidine triazole copper [I] binuclear complex luminescent material [[Cu[PPh3]2]2[mu-fpmtz]][ClO4]. The copper [I] binuclear complex luminescent material shows good solid-state luminescent properties, the maximum value of the solid-state luminescence wavelength is 531nm, the solid-state luminescence life is 18.1mus, and the solid-state luminescence quantum efficiency is 19.8%.

Description

technical field [0001] The invention relates to synthesis technology of new luminous materials, in particular to a copper [I] dinuclear complex luminescent material containing trifluoromethylpyrimidine triazole double chelating ligand and a preparation method thereof. Background technique [0002] Due to the influence of heavy atom effect and strong spin-orbit coupling, transition metal light-emitting complexes can theoretically utilize all singlet and triplet energy, and the luminous efficiency will be significantly improved. Currently, transition metal luminescent complexes are mainly based on fifth and sixth period transition metals, especially group VIII transition metals, such as ruthenium, osmium, iridium, and platinum. Since 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 difficult to mine, the cost of using such noble metal luminescent complexes is relatively high, an...
