Diarylaminofluorene-Based Organometallic Phosphors and Organic Light-Emitting Devices Made with such Compounds

Summary

This new phosphors can be applied on organic light-emitting diodes (OLED) applications. Thermally stable and solution-processable phosphors that suit for OLED applications are still under development. For example, fluorene based compounds are attractive candidates because of their good thermal and chemical stability, high emission quantum yields and the ease of functionalization. However, there is an issue of poor morphology during device fabrication. The present invention provides methods for solving the exisiting problems.

Technology Benefits

Chemically, thermally and morphologically stable, Strong emission, Significant improvements in device’s efficiency and Colors tunable

Technology Application

Manufacture OLED for the applications of solid-state lighting, black-light displays, full color displays, transparent and flexible displays

Detailed Technology Description

The present invention provides methods for obtaining highly amorphous and phosphorescent compounds comprising diarylaminofluorene groups, which offer low ionization potential, induce morphologically stable amorphous thin-film formation and good thermal stability. It also encompasses methods of tuning colors
