摘要

PPROBLEM TO BE SOLVED: To provide a new di-, tri- or tetra-phenylsilane skeleton-having fluorene compound useful as a host material having a high triplet energy level and a wide energy gap, to provide a light-emitting host material, a hole block material, and an organic EL element each containing the compound. PSOLUTION: This di-, tri- or tetra-phenylsilane skeleton-having fluorene compound is represented by the general formula (1) (RSP1/SPto RSP4/SPare each a group independently selected from the group consisting of H, straight or branched alkyl groups, optionally substituent-having aryl groups and optionally substituent-having heteroaryl groups; and RSP7/SPto RSP17/SPare each a group independently selected from the group consisting of H, straight or branched alkyl groups, and optionally substituent-having aryl groups). The light-emitting host material, the hole block material, and the organic EL element each containing the compound are provided. PCOPYRIGHT: (C)2008,JPO&INPIT
