AI Technical Summary

Problems solved by technology

However, cadmium-based quantum dots have safety concerns, and other quantum dots are significantly less efficient than cadmium-based quantum dots
In addition, quantum dots have the disadvantage of their poor stability against oxygen and water, and their performance is significantly degraded when aggregated
In addition, since it is difficult to maintain a constant size when producing quantum dots, the unit production cost is high

Embodiment 1

[0183] [Compound C]

[0184]

[0185] [Preparation Method C]

[0186]

[0187]

[0188] 5,5-difluoro-10-(methylthio)-5H-4l4,5l4-dipyrrolo[1,2-c:2',1'-f][1,3,2]diazepine Borane was dissolved in DCM, and benzylamine was added to the resulting solution, and the mixture was stirred at room temperature for 30 minutes. After the stirring was completed, the organic layer was extracted with dichloromethane, the extracted material was concentrated, and C-1 was synthesized by column chromatography. [M-F] + =277

[0189]

[0190] C-2 was prepared in the same manner as in the preparation of A-2, except that C-1 was used instead of A-1. [M-F] + =910

[0191]

[0192] Compound C was prepared in the same manner as in the preparation of Compound A, except that B-2 was used instead of A-2. [M-F] + =935

[0193] Method for manufacturing green film using [Compound C]

[0194] The prepared [Compound C] was used to produce a color conversion film emitting green light. Specifically, relative to 100% by...

Embodiment 2

[0199] [Compound D]

[0200]

[0201]

[0202] D-1 was prepared in the same manner as in the preparation of C-1, except that α-methylbenzylamine was used instead of benzylamine. [M-F] + = 291

[0203]

[0204] D-2 was prepared in the same manner as in the preparation of C-2, except that D-1 was used instead of C-1.

[0205]

[0206] Compound D was prepared in the same manner as in the preparation of Compound B, except that D-2 was used instead of C-2. [M-F] + =949

[0207] Method for manufacturing green film using [Compound D]

[0208] The prepared [Compound D] was used to produce a color conversion film emitting green light. Specifically, relative to 100% by weight of the SAN polymer, [Compound D] as a material emitting green light was added at a ratio of 0.4% by weight, and diffusion particles were added at a ratio of 3% by weight, and used in the n-butyl acetate solvent A solution with a solid content of 30% by weight was coated with a PET film to produce a color conversion film...

Abstract

The present specification relates to a nitrogen-containing cyclic compound, and a color conversion film, a backlight unit and a display device including the same.

Description

Technical field [0001] This specification claims the priority and rights of Korean Patent Application No. 10-2017-0180922 filed with the Korean Intellectual Property Office on December 27, 2017, the entire content of which is incorporated herein by reference. [0002] This specification relates to nitrogen-containing cyclic compounds and color conversion films, backlight units, and display devices containing them. Background technique [0003] A conventional light emitting diode (LED) is obtained by mixing a green phosphor and a red phosphor with a blue light emitting diode, or by mixing a yellow phosphor and a blue green phosphor with a UV light emitting diode. However, with such a method, it is difficult to control the color and therefore the color rendering is not good. Therefore, the color reproduction rate (color gamut) is poor. [0004] In order to overcome such a drop in color gamut and reduce production costs, a method of obtaining green and red colors by forming a film of ...
