Embodiment 1-4

Embodiment 1

[0029] At room temperature, put 10mmol of manganese chloride and 10mmol of dibromo-1,4-dipropyl-1,4-diazabicyclo[2.2.2]octane into a beaker respectively, at 10-15ml / min Slowly add distilled water and stir to dissolve. The volume of distilled water is 10mL, and then the two beakers are mixed with each other. After stirring evenly, stand at room temperature for 4 days to obtain the compound C with fluorescent properties. 12 h 26 N 2 Cl 4 Mn.

Embodiment 2

[0031] At room temperature, put 20mmol of manganese chloride and 10mmol of dibromo-1,4-dipropyl-1,4-diazabicyclo[2.2.2]octane into a beaker respectively, at a rate of 10-15ml / min Slowly add distilled water and stir to dissolve. The volume of distilled water is 10mL, and then the two beakers are mixed with each other. After stirring evenly, stand at room temperature for 5 days to obtain the compound C with fluorescent properties. 12 h 26 N 2 Cl 4 Mn.

Abstract

The invention discloses a divalent manganese fluorescent material based on dibromo-1,4-dipropyl-1,4-diazabicyclo[2.2.2]octane and its preparation method and application, belonging to molecular ion-based Divalent manganese fluorescent material. The chemical formula of the fluorescent material is C12H26N2Cl4Mn. At the temperature of 296K, the crystal belongs to the orthorhombic system, and the chiral space group is P212121. The product is prepared by mixing soluble salts containing Mn2+ and triethylenediamine derivatives and self-assembling with natural volatile solvents of the solution. The material preparation process adopted by the fluorescent material of the present invention is simple, easy to operate, sufficient source of raw materials, low production cost, high yield and good repeatability; the thermal decomposition temperature point is relatively high, and the crystal particles are uniform.

Description

technical field [0001] The invention belongs to the field of fluorescent materials, in particular to a divalent manganese fluorescent material based on dibromo-1,4-dipropyl-1,4-diazabicyclo[2.2.2]octane, a preparation method and application thereof. Background technique [0002] In the current energy shortage, energy conservation and environmental protection have become a major concern of all countries. Some countries have gradually banned the use of incandescent lamps and gradually phased out them, and promoted energy-saving and environmentally friendly fluorescent lamps. Photo-energy storage luminous powder is a fluorescent powder that stores light energy after being irradiated by self-identified light, daylight light, and ultraviolet light, and then slowly releases it in the form of fluorescence after stopping the irradiation, so it can be seen at night or in the dark. The light can still be seen. Due to these advantages of fluorescent lamps, they have gradually attracte...
