[0054] 2. Preparation and fluorescence test of the fluorescent material composition of the present invention

[0055] 2.1 Preparation of liquid fluorescent material composition and fluorescence test

[0056] 2.1.1 The preparation of the liquid fluorescent material composition follows three steps:

[0057] (1) Preparation of rare earth ion stock solution: weigh a certain molar amount of Eu 2 o 3 / or Tb 4 o 7 Put it into a beaker, dissolve it with 1:1 acid, heat it, add double distilled water repeatedly, evaporate the excess acid until the pH value is 3, and prepare a certain molar concentration with an appropriate amount of organic solvent (methanol / or ethanol). Rare earth ion Eu 3+ / or Tb 3+ stock solution.

[0058] (2) Preparation of the ligand stock solution: Weigh a certain molar amount of the ligand, add it to an organic solvent (methanol / or ethanol), stir, heat to dissolve it completely, cool it, and prepare it with (1) etc. Ligand stock solutions at molar conce...

Embodiment 1

[0083] Embodiment 1. The preparation of liquid fluorescent material composition, preparation steps are as follows:

[0084] 1. Preparation of rare earth ion stock solution.

[0085] (1) Weigh 0.01mol rare earth oxide Eu respectively 2 o 3 / or Tb 4 o 7 Put it in a beaker and dissolve it with 1:1 nitric acid;

[0086] (2) Place the beaker on a TYHW type electric heating mantle to heat, and repeatedly add double distilled water to evaporate excess nitric acid until the pH value is 3, and then use an appropriate amount of double distilled water to make 0.1mol / L rare earth ion Eu 3+ / or Tb 3+ stock solution.

[0087] (3) Take 1ml of the above Eu 3+ / or Tb 3+ Dilute the stock solution to the mark with methanol / or ethanol in a 100ml volumetric flask to obtain 1.0×10 -3 mol / L Eu 3+ / or Tb 3+ stock solution.

[0088] 2. Preparation of Ligand Stock Solution

[0089] (1) Add 0.01mol ligand and 40ml methanol / or ethanol to the beaker;

[0090] (2) Place the beaker in a DF...

Embodiment 2

[0095] Example 2 Preparation of solid fluorescent material composition.

[0096] The preparation steps are as follows:

[0097] (1) In a flask equipped with a reflux device, add 2.94 g (0.01 mol) of the ligand and 30 ml of methanol, and let it dissolve completely.

[0098] (2) The measured concentration is 0.1mol / L rare earth ion Eu 3+ / or Tb 3+ Add 33.3mL (0.0033mol) of the stock solution into the flask of (1), place the flask in a DF-II collector type magnetic heating stirrer, and heat under reflux for 30min.

[0099] (3) The flask was cooled, and a solid precipitated out. The solid is filtered, washed with methanol for 3 to 5 times, and then dried to obtain the solid fluorescent material composition of the present invention. The fluorescence spectrum can be measured.

Abstract

The present invention is liquid or solid fluorescent material composition comprising 4-methyl-3-cyan-2, 6-bis (3, 5-dimethyl-1-pyrazolyl) pyridine and RE ion Eu3+ or Tb3+. The new fluorescent material may be applied as fluorescent probe, etc in biochemical and chemical analysis.

Description

technical field [0001] The invention belongs to the technical field of fluorescent materials. Background technique [0002] There are many kinds of rare earth luminescent materials, and rare earth organic complex luminescent materials are one of them. [0003] Due to the unique structure and properties of rare earth ions themselves, after they are coordinated with organic ligands, the fluorescence emitted by rare earth ions has high luminous intensity, pure color and low light energy required by organic light-emitting compounds, high fluorescence efficiency, and easy The advantages of being soluble in organic materials provide a new idea for people to explore new luminescent energy sources and luminescent materials. This property of rare earth organic light-emitting complexes has a wide range of applications in the technical field, such as fluorescent probes and biomarkers in biochemistry and analytical chemistry. [0004] Rare earth complex prob...
