Title: New color-tunable metallophosphors of iridium(III) and platinum(II)
Speaker: Prof. Huang Weiyang (The Hong Kong Polytechnic University)
Venue: Meeting Room 402, North National Science Park of SCUT, Wushan Campus
Time: October 31, Thursday, 9:30
Owing to their unique electroluminescence (EL) ability of harnessing both singlet and triplet excitons, phosphorescent (triplet) emitters have brought revolutionary progress in the field of organic light-emitting diodes (OLEDs) by furnishing high EL efficiencies. In this talk, the recent developments of a new series of color-tunable iridium(IIII) and platinum(II) metallophosphors will be presented and their use in the full color and white OLED applications will be highlighted. A new electric field induced self assembly of a luminescent anionic platinum(II) complex [Pt(tfmpy)(CN)2]-Bu4N+ (tfmpy = 2-(4-(trifluoromethyl)phenyl)pyridine) 1 showing different nanostructures and distinct emission colors will also be described (Fig. 1).Figure 1. a) Diagram illustrating the setup for the investigation of the luminescence change of 1 under electric field and photographs of 1 (10 × 10–4 M) in acetonitrile before and after applying a voltage of 3 V under photoexcitation at 365 nm. b) Schematic diagram showing the formation of the rod-like and flower-like nanostructure of 1.
