Title of Paper:

Synthesis and photoelectric properties of bipolar host material 9-phenyl-3-( phenylsulfonyl) -6-( triphenylsilyl) -9H-carbazole

Journal:

Chinese Journal of Luminescence

Summary:

A new bipolar blue phosphorescent host material was synthesized and applied to phosphorescent organic light emitting diodes with Firpic (iridium (III) [bis (4, 6-difluorophenyl) -pyridinato-N, C2'] picolinate), the maximum current efficiency was 40 cd/A, maximum brightness was 19 691 cd/m2, maximum luminous efficiency was 12 lm/W. The results suggest that the host materials which we synthesized can better balance carrier injection and transport with appropriate triplet energy and goodly thermal stability.
