Platinum complex compound and organic electroluminescent device

Abstract

An organic electroluminescent device is provided and has at least one organic layer between a pair of electrodes. The organic compound contains a compound represented by the following formula (I): Z 1 and Z 2 each represents a nitrogen-containing aromatic 6-membered ring coordinating to platinum atom at the nitrogen atom, Q represents a nitrogen-containing aromatic 5-membered ring having one or two nitrogen atoms, L 1 and L 2 each represents a single bond or a divalent group, and n represents 0 or 1.

1 . A compound represented by formula (IIA): 
       
         
           
           
               
               
           
         
         wherein L 1  represents a single bond or a divalent linking group, and R 21 , R 22 , R 51 , R 52 , R 53 , R 54 , R 55  and R 56  each independently represents a hydrogen atom or a substituent.
