Abstract:
The purpose of the present invention is to provide an organic electroluminescent element having improved luminous efficiency and stability under high-temperature storage. The present invention is an organic electroluminescent element that has an anode, a cathode, and at least one light-emitting layer sandwiched between the anode and the cathode, and is characterized in that at least one of the light-emitting layers contains a π-conjugated boron compound having a structure represented by general formula (1). (In general formula (1), X 1  to X 9  each independently represents —CR or a nitrogen atom, R represents a hydrogen atom or a substituent, and Y 1  to Y 3  each independently represents an oxygen atom or a sulfur atom).

Claim (Index 8):
The organic electroluminescent element according to  claim 3 , wherein the electron-donating group represented by the W is represented by the following general formula 6: wherein: each R independently represents a hydrogen atom or substituent.
