title: Synthesis of dibenzothiophene-based host materials with a dimesitylborane substituent and their green PHOLED performances.
abstract: In the two isomeric dibenzothiophene-based host materials, the different linkages between dibenzothiophene and dimesitylborane on a phenyl spacer dictated their photophysical properties. The performances of Ir(ppy)2(acac)-based green phosphorescent devices with two isomeric host materials were similar regardless of different linkage positions.
