Electroluminescent Materials

Highly Luminous, Thermally Stable And Moisture-Resistant Light-Emitting Material Derived From Quadridentate Onno-Type Ligands And A Group 10 Metal Were Employed As Emissive Dopants In Organic Light-Emitting Devices. The Dopants Have Molecular Structures Represented By The Formula I And Ii:Wherein M Represents Group 10 Metal (Including Platinum) And R1-R14 Are Each Independantly Selected From The Group Consisting Of Hydrogen; Halogen; Alkyl; Substituted Alkyl; Aryl; Substituted Aryl, With Substitutents Selected From The Group Consisting Of Halogen, Lower Alkyl And Recognized Donor And Acceptor Groups.published_or_final_versio
