Description
Technical Field
The invention relates to the field of organic electroluminescent materials and devices, in particular to an OLED (organic light emitting diode) main body material based on a triptycene framework as well as a preparation method and application thereof.
Background
Organic Light Emitting Diodes (OLEDs), as a new generation display technology, have the advantages of low cost, low power consumption, flexibility, rich colors, wide viewing angles, etc., as compared to conventional displays, and are increasingly used in the fields of solid state lighting, flat panel display, etc. With the development of research, the light emitting materials have been also expanded to the third generation, the first generation OLED material is a conventional fluorescent molecule, the second generation is a phosphorescent OLED material, and the third generation Thermal Activated Delayed Fluorescence (TADF) material, wherein the phosphorescent OLED material and the thermal activated delayed fluorescence material can effectively utilize 75% of triplet excitons so as to obtain high External Quantum Efficiency (EQE), but the stability and lifetime of the device limit the practical application thereof. Fluorescence quenching is one of the important factors influencing the performance of the OLED device, and people can uniformly disperse guest molecules in a host material by selecting a proper host material and utilizing host-guest doping to enhance the performance of the OLED device, so that the host material can reduce the concentration fluorescence quenching on one hand, and can transfer the energy of the host material to the guest material through energy transfer on the other hand, thereby improving the performance of the OLED device.
Currently, a large number of new OLED light-emitting layer guest materials have been developed, in contrast to the relatively late research of host materials for OLED devices. The triptycene is a molecule with a non-planar structure, has a larger framework and a larger cavity, is beneficial to uniform dispersion of small molecular materials, and inhibits the aggregation quenching effect of the small molecular materials, thereby improving the efficiency of an OLED device.
