Synthesis and blue phosphorescent device performances of a new bipolar host material containing pyrazino[2,3-b]indole moiety?
RSC Advances Pub Date: 2014-10-16 DOI: 10.1039/C4RA10307F
Abstract
A new bipolar host material (CzPhPz) consisting of 5H-pyrazino[2,3-b]indole unit was synthesized and its photophysical properties and device performances were investigated. It showed good electron transport properties with a high triplet energy of 2.83 eV. CzPhPz was effective as the host material for FIrpic-based blue PHOLED with a high quantum efficiency of 15.0%.
