<p>A polycyclic ring assembly compound which has a specific flexible partial structure, i.e., a structure comprising 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 comprising the polycyclic ring assembly compound or the polymer; and an organic electroluminescent device. The organic electroluminescent device has excellent heat resistance, a high color purity, and a long life and can emit a blue light or green light at a high luminescent efficiency. The polycyclic ring assembly compound realizes the device.</p> |
