Description
Technical field
The present invention relates to light conversion film, and in particular to a class contains tetraphenyl ethylene group has aggregation-induced emission property
Green glow dyestuff, optical conversion film is made by solution spin coating, be can be applied to plane and is shown.
Background technology
With display industry technology continuous breakthrough and the market demand increasingly increase, flat-panel monitor with its small volume,
Lightweight, power consumptive province, radiate the series of advantages such as small, Electro Magnetic Compatibility is good and emerge rapidly, the master as 21 century Display Technique
Stream.Flat-panel monitor plays very important effect into color mode in its production process, and its quality directly determines flat
The color developing effect of panel display, production cost and service life.
Current flat-panel monitor realizes that the mainstream technology of colored display is prepared by printing red, green, blue fluorescent material with three basic colour
Device, however, because the life-span of fluorescent material with three basic colour and the dough softening differ greatly, it is easy to cause the inclined of color monitor
Color, and the manufacture craft of three primary colors device is more complicated, it is relatively costly.In order to solve these problems, people open and propose one
The new approaches for planting color conversion are " color-by blue "." color-by blue " technology is made using the blue emitting phophor with single high brightness
It is backlight, the blue light that backlight sends shows by being transformed into feux rouges and green glow after color conversion coatings film so as to realize that RGB is full-color
Show.This technology can not only greatly simplify the production technology of electroluminescent flat-panel screens, improve the color stable of display
Property and uniformity, and the production cost of display can also be significantly reduced.For color conversion coatings film material can be divided into it is inorganic and
Organic two major class.It has been investigated that, relative to inorganic fluorescent powder, not only there is organic transition material color conversion higher to imitate
Rate, color also more saturation, such that it is able to realize broader colour gamut, and raw material is cheap and easy to get, it is easier to carry out cutting out for molecule
With modification obtaining more preferable display effect.
The nineties in 20th century, it is green light material that Leising team uses Coumarins dyestuff Coumarin 102,
Lumogen F300 are prepared for green, red light conversion film for red dye is dispersed in PMMA, obtain red more than 10%
Light conversion efficiency (bibliography：Adv.Mater.,1997,9(1),33-36).Recent year research team is also to organic light
(bibliography is reported in the preparation for changing film：Optoelectronics Letters,2010,6(4),245-248,
CN105267059 A, CN103647003 A), obtain colour gamut extensively, the organic light transform film of light high conversion rate..
Organic fluorescence color conversion coatings film is usually that the organic fluorescent dye with different colours is passed through into ultra-violet curing or heat
The modes such as solidification are evenly dispersed in macromolecular solid body thin film, then with the Blue backlight source excitation organic fluorescence color of high brightness
The dye molecule in film is changed to realize the transformation of color, the blue light of the feux rouges being converted to, green glow and background forms the three of light
Primary colours are planted, the full-color EL display of electroluminescent cell may finally be realized.
However, be susceptible to assemble and cause fluorescent quenching between the organic dye molecule for generally using, in filminess
Hardly light, therefore in these light conversion film materials, organic dyestuff is usually to be disperseed with very low concentration (some thousandths of)
In transparent macromolecule resin, too low concentration frequently can lead to incomplete absorption of the film to light, it is desirable to obtain sufficient light
Conversion effect must just increase the thickness of film, so as to cause the increase of whole display panel thickness.
This loyal academician of the Tang of Hong Kong University of Science and Thchnology proposes the concept of aggregation-induced emission (AIE), the molecule of this kind of AIE types
In solid-state with quantum yield very high, molecule its solid state quantum yield (QY) constituted with diazosulfide and tetraphenyl ethylene
89% (bibliography is reached：Chem.Commun., 2011,47,8847-8849), this quasi-molecule is widely used in biology
Fluorescence probe, ion detection, oled emitting layer materials etc., but its application in organic light transform film material does not appear in the newspapers but
Road, high quantum production rate of the AIE types molecule in solid-state makes its application in this field have natural advantage.
