Description
Technical field
The invention belongs to electroluminescent organic material technical fields, and in particular to a kind of asymmetric to receptor type organic red light
Fluorescent small molecule material and its application in organic electroluminescence device is prepared.
Background technology
Organic electroluminescent LED (OLEDs) is rollable, bright in luster with low energy consumption, wide viewing angle, low cost, flexibility
The advantages that, promise to be next-generation display and illuminating device.At present, the display screen based on OLEDs technologies have been supplied in mobile phone,
On TV and computer.But the material and device process technology of current OLEDs are still immature.Material is the technology core of OLEDs
The heart.The material applied in display screen is had been commercialized at present, the overwhelming majority is centered on precious metal iridium (Ir) or platinum (Pt)
Metal complex phosphor material.But Ir and Pt are scarce resources, and it is expensive, being produced into for OLEDs will necessarily be increased
This.Secondly, Ir and Pt is the precious resources that China has strategic importance, is not suitable for the utilization of long term commercial.In addition,
The metalcomplex sythesis of Ir and Pt is difficult, and main ligand and assistant ligand selection are limited, are difficult to realize the diversification of molecular structure.
Organic red fluorescent small molecule is without precious metal, mainly by elements groups such as C, H, O, N, P, S of nature content very abundant
Into synthesis cost is more cheap.Molecular structure Modulatory character is strong, can synthesize a variety of differences by abundant methodology of organic synthesis
The molecule of structure, material structure are ever-changing.Therefore, organic red fluorescent small molecule has abundanter photophysical property,
It can realize abundanter color displays.But constrained by spin statistics, in OLEDs devices, singlet and triplet state swash
Sub- generation ratio is 1:3, that is, singlet exciton production rate is only 25%.For organic red fluorescent small molecule, only singly
Line state can shine, and account for the exciton generation most of triplet state of ratio and be dissipated in the form of nonradiative transition, cause huge
Waste.Metal complex phosphor material can realize that 100% exciton utilizes, this is metal complex phosphor material relative to organic
The main advantage of red fluorescence small molecule fluorescent material.Meet actual displayed or illumination needed for brightness generally require it is larger
Current density.But triplet excitons radiation transistion rate is slow, lasts a long time.Under big current density, triplet excitons
Having little time rapidly to return to ground state in the form of radiation transistion, this can cause a large amount of accumulations of triplet excitons, easily be quenched,
For example singlet-triplet state is quenched, and triplet state-triplet state is quenched, and triplet state-charge is quenched etc., this leads to metal combination
Object phosphor material often will appear serious efficiency roll-off in high brightness.Therefore, exploitation breaks through the organic red of exciton statistics
Fluorescent small molecule material realizes high efficiency under high brightness, and to pushing OLEDs, further commercialization is of great significance.
Feux rouges is essential in total colouring.Although the performance of the red phosphorescence material based on Ir and Pt is good
Meet commercialization requirement, but the noble metals such as Ir and Pt are expensive, be not suitable for long period of development.And organic fluorescence materials cost is honest and clean
Valency, but red fluorescence material efficiency is also than relatively low at present.So exploitation commercial presenceization can practical application high efficiency it is red
Fluorescent material is extremely important.Using asymmetry to acceptor molecule design concept, design synthesis have D (donor)-A (receptor)-
A ' (receptor) or D (donor)-A (receptor)-D ' (donor) type molecule, can realize the diversification of material structure.Meanwhile it compares
It is asymmetric that abundanter photochromic and excitation is advantageously implemented to receptor type molecular design method in traditional D-A type molecules
State property matter.In addition, the asymmetric MOLECULE DESIGN to receptor type material is conducive to introduce function difference simultaneously in same intramolecular
Group, realize that molecule has multiple functions, be conducive to improve the photoelectric properties of material.By introducing have triplet state-
Show state bury in oblivion (TTA) property to receptor unit, connected by way of linear conjugate, not only contribute to realize efficient
Red emission can also obtain high efficiency under high illumination by TTA mechanism using triplet state.
