Taking advantage of inorganic click (iClick) and aurophilic interactions complexes {[PEt3Au]2(μ-N3C2)-9,9-dioctyl-9H-fluorene}2 (Au4-FO) and [PPh3Au]2(μ-N3C2)-9,9-dioctyl-9H-fluorene (Au2-FO) were inserted into OLEDs to give voltage dependent light. Varying the voltage and percent of Au present in the OLED yields light that has the colors white, blue, red, and green as confirmed using 1931 CIE color space. Au4-FO and Au2-FO were synthesized via iClick and exhibit both fluorescence and phosphorescence in solution and in the device. The device was fabricated with the structure ITO/PEDOT:PSS/PVK:PBD:Au/LiF/Al. The turn on voltage ranged depending on the percent of Au present in the emissive layer, the lowest voltage observed was 14 V.
