Highly rigid and twisted anthracene derivatives: a strategy for deep blue OLED materials with theoretical limit efficiency

Abstract

New highly twisted and rigid blue materials composed of anthracene with xylene as the core unit and either naphthalene or phenyl end units were synthesized. Non-doped devices using BDNA displayed 5.26% maximum external quantum efficiency with CIE color coordinates (x, y: 0.159, 0.072).
