Spiro bifluorene compounds as organic semiconductor matrix materials

摘要

Use of an organic matrix material (A) for the preparation of an organic semi-conductor material, comprises at least partly spiro bifluorene compound (D), where glass transition temperature of (A) is at least 120[deg]C and the highest occupied molecular orbital (HOMO) of the matrix material is at most on an energy level of 5.4 eV. Use of an organic matrix material (A) for the preparation of an organic semiconductor material, comprises at least partly spiro bifluorene compound (D) of formula (I) and/or formula (II), where glass transition temperature of (A) is at least 120[deg]C and the highest occupied molecular orbital (HOMO) of the matrix material is at most on an energy level of 5.4 eV. R : a substituent at phenyl residue (where not all R are simultaneously hydrogen); and R 1>a substituent. Independent claims are also included for: (1) an organic semiconductor material comprising (A) and an organic dopant; and (2) an electronic element comprising an organic semiconductor material.
