1. A metal complex comprising an Ir atom, an ancillary ligand, wherein the ancillary ligand is picolinate or substituted picolinate, and at least one ligand which coordinates to the Ir atom through a carbon atom, the ligand which coordinates to the Ir atom through a carbon atom represented by any of the following formulae: wherein R1 to R6, independently from another may be the same or different and are selected from the group consisting of alkyl, alkoxy, and non-aromatic rings, Y is a substituent other than hydrogen and p is an integer from 0 to 4. |
