Four compounds 4-[3,6-di(carbazol-9-yl)carbazol-9-yl]isoquinoline (TCIQ), 3-[3,6-di(carbazol-9-yl)carbazol-9-yl]pyridine (TCPy), 4-(carbazol-9-yl)isoquino-line (4CIQ), and 3-(carbazol-9-yl)pyridine (Cpy) containing pyridyl or isoqui-nolyl were designed and synthesized to co-deposition with copper iodide (Cul) to form luminescent Cu(Ⅰ) complex doped film in situ, which could be utilized as the emissive layer in organic light-emitting diodes (OLEDs). It is found that simple tri-layered yellow and white OLEDs can be achieved by co-depositing Cul and TCIQ with tuning ratios. The compound TCIQ serves a dual role as both a ligand for forming the emissive Cu(Ⅰ) complex and as a host matrix for the formed emitter in yellow OLEDs, and a third role as a blue emitter in white OLEDs.
