Title:
多環系環集合化合物及びそれを用いた有機エレクトロルミネッセンス素子
Document Type and Number:
Japanese Patent JP5715336
Kind Code:
B2
Abstract:
Polycyclic ring assembly compound which has a specific flexible partial structure, i.e., a structure containing an aromatic ring in which adjacent carbon atoms have, bonded thereto, an aromatic ring group of another kind and an aliphatic group or aromatic ring group. Also provided are: a polymer constituted of repeating units at least part of which are structures derived from the polycyclic ring assembly compound; a solution of an organic EL material containing the polycyclic ring assembly compound or the polymer; and an organic electroluminescence device. The organic electroluminescence device has excellent heat resistance, high color purity, and a long lifetime and can emit a blue light or green light at a high luminescent efficiency. The polycyclic ring assembly compound realizes the device.
