Embodiment 1

[0032] CuCl 2 2H 2 O, 2-(1H-pyrazol-3-yl)pyridine was added to the inner tank of the reactor at a molar ratio of 1:0.5, and 17ml of acetone was added to the inner tank of the reactor, sealed and reacted at a temperature of 160°C 72h. Naturally cooled to room temperature, the chemical formula obtained is C 16 h 12 N 6 C1 4 Cu 2 crystals, yield: 70% (with CuCl 2 2H 2 O calculation). After the complex is excited by light of λex=325nm, a strong characteristic fluorescence appears at λem=365nm.

Embodiment 2

[0034] CuCl 2 2H 2 O, 2-(1H-pyrazol-3-yl)pyridine was added to the inner tank of the reactor at a molar ratio of 1:1, and 12ml of deionized water was added to the inner tank of the reactor, sealed, and kept at a temperature of 140°C Under the reaction 60h. Naturally cooled to room temperature, the chemical formula obtained is C 16 h 12 N 6 Cl 4 Cu 2 crystals, yield: 65% (with CuCl 2 2H 2 O calculation). After the complex is excited by light of λex=325nm, a strong characteristic fluorescence appears at λem=365nm.

Embodiment 3

[0036] CuCl 2 2H 2 O, 2-(1H-pyrazol-3-yl)pyridine was added to the inner tank of the reactor at a molar ratio of 1:2, and 15ml of DMF was added to the inner tank of the reactor, sealed, and reacted at a temperature of 130°C 36h. Naturally cooled to room temperature, the chemical formula obtained is C 16 h 12 N 6 Cl 4 Cu 2 crystals, yield: 61% (with CuCl 2 2H 2 O calculation). After the complex is excited by λex=325nm light, a strong characteristic fluorescence appears at λem=365nm.

Description

technical field [0001] The invention belongs to the field of coordination chemistry, and specifically relates to a 2-(1H-pyrazol-3-yl)pyridine copper complex and a preparation method thereof; and the application of the complex in the preparation of fluorescent materials. Background technique [0002] Luminescent materials are classified in the form of compound valence bonds. One category is organic materials, which are combined into organic compounds in the form of covalent bonds. Organic materials include small molecules and polymer materials; for inorganic materials, general powder materials The basic unit of the composition is a microcrystal, and most of the III-IV and II-VI semiconductor light-emitting materials are single crystals. In the process of photoluminescence, when a substance absorbs light radiation and is excited, there are often two emission processes, one is that the luminescence delay after the excitation is stopped is very short, which is called fluorescen...
