Title:
高分子カルバゾール化合物
Document Type and Number:
Japanese Patent JP2009524703
Kind Code:
A
Abstract:
A polymeric carbazole compound comprising a monomer unit of formula (I): is disclosed, wherein x and y are equal to zero or 1, and n is an integer equal to or larger than zero. P represents a phenyl group, and C1, C2 and C3 represent carbazole units. The derealization of the triplet wave function over the biphenyl structure is decreased by introducing twists in the polymer backbone at the location where the two carbazole units are connected, whereby the triplet energy is increased. The twist is introduced by substituents, e.g. methoxy or 3,7-dimethyloctyloxy. The polymeric carbazole compound may be used as a semiconducting material. The semiconducting material may be used as a host matrix for luminescent emitters.
