LIGHT-EMITTING METAL COMPLEX AND DEVICE

LIGHT-EMITTING METAL COMPLEX AND DEVICE

A phosphorescent metal complex comprising at least one ligand substituted with a group of formula (Bla), (Mb) or (Mc): wherein Y is selected from 0, S, a substituted carbon atom; and a substituted silicon atom ; Z in each occurrence is independently selected from N and P; R4 independently in each oc...

Beschreibung
Zusammenfassung:A phosphorescent metal complex comprising at least one ligand substituted with a group of formula (Bla), (Mb) or (Mc): wherein Y is selected from 0, S, a substituted carbon atom; and a substituted silicon atom ; Z in each occurrence is independently selected from N and P; R4 independently in each occurrence is a substituent; R5 independently in each occurrence is H or a substituent; x independently in each occurrence is 0, 1, 2 or 3; y and z in each occurrence are independently 0, 1, 2, 3 or 4. The group of formula (Ma), (Illb) or (IIIc) may be directly bound to the ligand or spaced apart therefrom by a spacer group. The phosphorescent metal complex may be used as a light-emitting material in an organic light-emitting device.
