AbstractA new phosphorescent material of bis-cyclometalated alkynylgold(III) complex has been synthesized, characterized, and its device performance investigated. This luminescent gold(III) complex was found to exhibit rich photoluminescence (PL) and electroluminescence (EL) properties, and has been utilized as phosphorescent dopants in organic light-emitting diodes (OLEDs). At an optimized dopant concentration of 4 %, a device with a maximum external quantum efficiency (EQE) of 11.5 %, corresponding to a current efficiency of 37.4 cd/A and a power efficiency of 26.2 lm/W, has been obtained. Such a high EQE value is comparable to that of Ir(ppy)3-based devices. The present work suggests that the alkynylgold(III) complex is a promising phosphorescent material in terms of both efficiency and thermal stability.
