摘要：

A new approach to full-color printable phosphorescent organic light-emitting devices (P(2)OLEDs) is reported. Unlike conventional solution-processed OLEDs that contain conjugated polymers in the emissive layer, the P(2)OLED's emissive layer consists of small-molecule materials. A red P(2)OLED that exhibits a luminous efficiency of 11.6 cd/A and a projected lifetime of 100,000 hours from an initial luminance of 500 cd/m(2), a green P(2)OLED with a luminous efficiency of 34 cd/A and a projected lifetime of 63,000 hours from an initial luminance of 1000 cd/m(2), a light-blue P(2)OLED with a luminous efficiency of 19 cd/A and a projected lifetime 6000 hours from an initial luminance of 500 cd/m(2), and a blue P(2)OLED with a luminous efficiency of 6.2 cd/A and a projected lifetime of 1000 hours from an initial luminance of 500 cd/m(2) is presented.
