Abstract

A blue iridium carbene complex realizes high-efficiency blue and white OLEDs (see figure). For a blue OLED, ηp,max is recorded to be 35.9 lm W−1. For a white OLED, ηp,max and ηp,1000 are measured to be 59.9 lm W−1 and 43.3 lm W−1, respectively, without any light-outcoupling enhancement. This white OLED also shows an illumination-acceptable CRI over 80. Detailed facts of importance to specialist readers are published as "Supporting Information".
