Bis(carbazolyl)benzodifuran: A High‐Mobility Ambipolar Material for Homojunction Organic Light‐Emitting Diode Devices

Abstract

A new ambipolar material bis(carbazolyl)benzodifuran (CZBDF) shows well-balanced and high carrier mobilities for both holes and electrons (>10−3 cm2 V−1 s−1). This new material allows us to fabricate efficient p-i-n homojunction OLEDs that emit light across the full visible color range and perform at a level similar to state-of-the-art heterojunction devices.
