Polycyclic aromatic compound and method for production the same, material for organic device and application thereof

The invention provides a novel polycyclic aromatic compound and an organic electric field light-emitting element using the same. By providing a new type of polycyclic aromatic compound in which a plurality of aromatic rings are connected by a boron atom and an oxygen atom, etc., options for materials for organic EL devices are increased. In addition, by using a novel polycyclic aromatic compound as a material for an organic electric field light emitting device, an excellent organic EL device is provided.
