Extremely deep blue and highly efficient non-doped organic light emitting diodes using an asymmetric anthracene derivative with a xylene unit

Abstract

A new highly twisted asymmetric anthracene derivative with naphthalene and triphenylamine substituted xylene was synthesized as an extremely deep blue emitting material. A non-doped device using the new asymmetric blue emitter displays a maximum EQE of 4.62% with CIE color coordinates of (0.154, 0.049).
