Abstract

A light-emitting device comprising a pair of electrodes, and organic compound layers comprising a light-emitting layer provided in between the electrodes, wherein at least one of the organic compound layers comprises a compound having a transition metal atom-phosphorus atom bond.

Claims

exact text as granted — not AI-modified
1 . A light emitting device comprising: 
 a pair of electrodes; and    organic compound layers comprising a light-emitting layer provided in between the electrodes,    wherein at least one of the organic compound layers comprises a compound having a transition metal-phosphorus atom bond, and    wherein the compound having a transition metal-phosphorus atom bond is represented by formula (1):                          wherein M 1  represents rhodium (III), tungsten (O), or rhenium (I), R 1  represents a hydrogen atom or a substituent, L 1  represents a ligand, X 1  represents a counter ion, n 1  represents 2 or 3, n 2  represents an integer of 1 to 8, n 3  represents an integer of 0 to 8, n 4  represents an integer of 0 to 6, when at least one of n 1 , n 2 , n 3  and n 4  is more than one, R 1  groups, (R 1 ) n1 —P ligand, L 1  ligands or X 1  ions are each the same or different.    
     
     
         2 . The light-emitting device according to  claim 1 , wherein at least one of R 1  represents a heteroaryl group.  
     
     
         3 . The light-emitting device according to  claim 1 , wherein at least one of R 1  represents a heteroaryloxy group.  
     
     
         4 . The light-emitting device according to  claim 1 , wherein at least one of R 1  represents a substituted amino group.  
     
     
         5 . The light-emitting device according to  claim 1 , wherein a plurality of R 1  combine with each other to form a cyclic structure.  
     
     
         6 . The light-emitting device according to  claim 1 , wherein a plurality of R 1  combine with each other to form a phosphinine ring.  
     
     
         7 . The light-emitting device according to  claim 1 , wherein at least one of R 1  represents an alkoxy group.  
     
     
         8 . The light-emitting device according to  claim 1 , wherein at least one of R 1  represents an aryloxy group.
