Electroluminescent material, electroluminescent element and color conversion filter

An electroluminescence element comprising an electroluminescent material and an inorganic fluorescent substance capable of emitting light having a wavelength of a maximum emission different from that of light emitted from the electroluminescent material upon absorption of the light emitted from the electroluminescent material, and the electroluminescent material is a compound represented by the following Formula C1:

• Formula C1
• 74
• wherein Ar51 is an aryl group or an aromatic heterocyclic group;
• n is an integer of from 0 to 6;
• L21, L22, L23, L24, L25 and L26 are a group of atoms necessary to form a 6-member nitrogen-containing aromatic heterocyclic group, provided that at least one of L21, L22, L23, L24, L25, and L26 is ═N— or —N(R51)—;
• R51 is a hydrogen atom or a substituent, provided that at least one of Ar51 and R51 is a biaryl group having a bond capable of giving an internal rotational isomerism or a group making the biaryl group, provided that adjacent substituent groups existing in the molecule represented by formula C1 may be condensed with each other to form a ring.
