This project aims to develop a new class of patentable gold(III)-containing triplet light-emitting materials with tunable emission colours for the applications of high-performance solution-processable OLEDs, based on the recent successful demonstration by the Principal Investigator of a novel class of gold(III) complexes that exhibit intense photoluminescence (PL) as well as their superior performance as electrophosphorescent dopants for the fabrication of solution-processable OLEDs. The present project focuses on the design and synthesis of gold(III) complexes with tunable PL colours spanning over the entire visible spectrum; particularly, an in-depth study on their energy levels will be probed by electrochemical techniques and density functional theory calculations. The application studies employing these gold(III) complexes as phosphors for the fabrication of solution-processable OLEDs will also be explored, in which colorful OLED devices and white light-emitting OLEDs (WOLEDs) based on the proprietary materials will be made. It is envisaged that the present project not only will offer a new class of triplet light-emitting materials with tunable emission colours, but can also generate Hong Kong-owned IP rights and important technological know-how for knowledge and technology transfer. This technology will no doubt be of great benefit to display and solid-state lighting companies, and more importantly, it can establish a platform for facilitating the collaboration with industries in the Mainland and the Guangdong Province region for motivating downstream R&D and commercialization activities.
