摘要

4-Bromo-9,9′-spirobifluorene is facilely synthesized, and from this precursor, two ortho-linked oligo-9,9′-spirobifluorenes, 44BSF and 24TSF, are constructed. Devices with 24TSF as the full-hydrocarbon host material and lr(ppy)₃ or (ppq)₂lr(acac) as the triplet emitter show maximum external quantum efficiencies of 12.6 and 10.5% for green and red electrophosphorescence, respectively.
