A material for organic electroluminescent devices is characterized by being represented by the following general formula (I). In the formula, R1 and R2 independently represent a substituent; A1 represents a residue necessary for forming an aromatic carbocyclic ring or a heterocyclic ring; L represents a linking group; X represents an element having an unpaired electron and capable of forming a coordinate bond with a boron atom; Rx represents a hydrogen atom, aliphatic group, aromatic group or heterocyclic group; n represents 0 or 1; m represents 1 or 2; Rx may be bonded with an arbitrary element of L to form a ring; R1 and R2 may combine together to form a ring; and Rx may be bonded with an arbitrary element of A1 to form a condensed ring. |
