The Right

A blue organic light-emitting diode (OLED) with a double hole-transporting (DHT) structure has been developed. The blue color purity was improved by modulation the thickness of CBP layer. When the thicknesses of left CBP and right CBP are respectively 8 nm and 2 nm, the more pure blue coordinates are (0.155, 0.079), which are very close to the blue coordinates of the national television system committee (NTSC) standard (0.14, 0.08). Furthermore the current density, brightness and the luminous efficiency of device with the left CBP of 8 nm and the right CBP of 2 nm are respectively 144.7 mA/cm2, 1065 cd/m2 and 0.93 cd/A.

Cie Chromaticity

Two deep blue-emitting dendrimers 11 and 12 with carbazole containing dendrons were developed in this contribution. The carbazole-containing units were introduced to tune the charge-transporting property of the desired dendrimers. The investigation of photophysical properties, electrochemical, and electroluminescence properties demonstrated that the balance between electron and hole transporting was achieved from both dendrimers. The preliminary organic light-emitting diode (OLED) fabrication achieved a pure blue colour with stable CIE chromaticity coordinates (X: 0.15–0.16, Y: 0.09–0.10) for 11 and 12. Single layer deep blue emitting diode devices with higher efficiency are achieved without the colour changing. The investigation of OLED performance indicates that dendrimers 11 and 12 are promising light-emitting materials with pure blue colour and good colour stability for OLEDs.
