Abstract: In order to provide a novel π-conjugated compound capable of increasing the light-emission efficiency of an organic electroluminescence element, for example, this π-conjugated compound has a structure indicated by general formula (1). (In general formula (1): Z1-Z6 each independently indicate a hydrogen atom, a deuterium atom, an electron-donating group D, or an electron-withdrawing group A; at least out of two among Z1-Z6 is an electron-donating group D and the other is an electron-withdrawing group A; and at least one ortho position combination Z1 and Z2, Z2 and Z3, Z3 and Z4, Z4 and Z5, Z5 and Z6, or Z6 and Z1 among Z1-Z6 is one combination out of an electron-donating group D and an electron-donating group D, an electron-withdrawing group A and an electron-withdrawing group A, or an electron-donating group D and an electron-withdrawing group A.)

Abstract: There are provided a π-conjugated boron compound, an electronic device containing an organic functional layer including the π-conjugated boron compound, a method for producing a triarylborane, and a method for producing a triarylborane intermediate. In the π-conjugated boron compound, a boron atom is bonded to three aromatic groups via three boron-carbon bonds. Bond distances of the three boron-carbon bonds are all 1.48 Å or less.

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), X1 to X9 each independently represents —CR or a nitrogen atom, R represents a hydrogen atom or a substituent, and Y1 to Y3 each independently represents an oxygen atom or a sulfur atom).
