Efficient and low roll-off deep-blue organic light-emitting diodes with anthracene-based compounds as hosts

Abstract

In this work, we synthesized and characterized four bipolar host materials, which were 9-(naphthalen-1-yl)-10-(4-(naphthalen-2-yl)phenyl) anthracene (NA-AN-NA), 1-(4-(10-(naphthalen-1-yl)anthracen-9-yl)phenyl) dibenzo[b,d]furan, 1-(4-(10-phenylanthracen-9-yl)phenyl) dibenzo[b,d]furan, and 2-(4-(10-phenylanthracen-9-yl)phenyl) dibenzo[b,d]furan. These four materials possessed good thermal stability...
